\((x+2)(x+3)\)
Step-by-step explanation:
⭐What does factorisation mean?
factorisation is the process of writing a number or a polynomial in terms of its factors⭐What are factors?
factors are the terms that multiply together to create a number or a polynomialThus, we have to write \(x^2+5x+6\) in terms of its factors.
I have a picture attached to this response to show you how factorisation works, but I will also explain it here.
How to factorise:
Look at the constant in your polynomial (the term without a variable). In this problem, the constant is 6. Look at the coefficient middle term in your polynomial (the number next to the variable). In this problem, the middle coefficient is 5. Find what numbers multiply together to have a product of 6, and add together to have a sum of 5.The numbers +2 and +3 multiply together to have a product of 6, and add together to have a sum of 5. In the next line, write the polynomial again, but write 5x in terms of the numbers we found.You'll get: \(x^2 + 2x +3x + 6\)Now, we can factorise the binomials we see here.⭐What are binomials?just as "bi" means 2, binomials are equations with 2 termsThe binomials are \(x^2 + 2x\) and \(3x + 6\)To factorise the binomials, find the GCF for both terms of each binomial.The GCF for \(x^2 + 2x\) is x.The GCF for \(3x+6\) is 3.Now, write the GCFs outside of the parentheses for each binomial and rewrite what's in the parentheses.You'll get: \(x(x+2) +3(x+2)\)You should have the same expression in both parentheses.Now, we have to rewrite this expression by keeping what's inside of the parentheses, and putting the terms outside of the parentheses inside parentheses.You'll get: \((x+2)(x+3)\)That's it!The picture of factorisation is attached to this response.

which type of transformation preserves the symmetry of an even function f(x) but does not preserve the symmetry of an odd function g(x)?vertical translationhorizontal translationreflection over the x-axisreflection over the y-axis
Answers
The type of transformation that preserves the symmetry is Vertical translation.
For instance, a parabola is still symmetric about the y-axis if you move it up. It loses its symmetry if you move it to the left or right. Reflection keeps both even and odd functions symmetrical.
What is the difference between even and odd function ?The symmetry of a function is described using the terms even and odd. On a graph, an even function is symmetric about the y-axis. An odd function has symmetric behavior around a graph's origin \((0, 0)\). This means that if you rotate an odd function 180 degrees around the origin, the function you started with will still exist.

The value of 41 squared is between which two whole numbers?
Answers
The image shows the square root of 41
The root of 41 in decimal is 6.403.
As such the integers before and after 6.403 are 6 and 7
Another way to solve this is to consider the perfect square before 41 which is 36.
The square root of 36 is 6. Since 41 is higher than 36, the number before root 41 would be 6 and the next number after 6 is 7.
Hence the two numbers before and after √41 are 6 and 7
Kiera needs to make copies. The copy place charges a one time fee of $1.89 for any order, then $0.05 per copy. Find the equation of the line that describes the cost of making the copies in slope intercept form, y=mx+b.
Answers
The slope-intercept form of the equation that describes the cost of making the copies is \(y = 0.05x + 1.89\).
Let x be the number of copies and y be the cost of making the copies.
According to the problem, the copy place charges a one-time fee of $1.89 for any order, then $0.05 per copy.
This can be expressed as:
\(y = 0.05x + 1.89\)
This is in slope-intercept form, where m is the slope and b is the y-intercept. In this case, the slope is 0.05, which means that for every additional copy, the cost increases by $0.05. The y-intercept is 1.89, which represents the one-time fee charged for any order.
Therefore, the equation of the line that describes the cost of making the copies in slope-intercept form is \(y = 0.05x + 1.89\).

debbie has at most $60 to spend on the clothes. she wants to buy a pair of jeans for $22 and spend the rest on t-shirts. each t-shirt cost $8. what is the greatest number of t-shirts debbie can buy. *
Answers
Debbie can buy a maximum of 4 t-shirts with the remaining $38 after purchasing the $22 jeans.
To determine the greatest number of t-shirts Debbie can buy, we need to find out how much money she will have left after purchasing the pair of jeans. Debbie has $60 to spend and the jeans cost $22. Therefore, she will have $60 - $22 = $38 left to spend on t-shirts.
Each t-shirt costs $8, so we divide the remaining amount by the cost per t-shirt: $38 / $8 = 4.75.
Since Debbie cannot buy a fraction of a t-shirt, we round down the decimal value to the nearest whole number. Therefore, Debbie can buy a maximum of 4 t-shirts with the remaining $38.

Pls help ASAP An operation * is defined on the set of real numbers R by a*b=a³+b³ -3ab for all a,b is an element of R. Is the Operation * commutative
Answers
Answer:
The operation is commutative
Step-by-step explanation:
Operations
The * operation is defined on the set of real numbers R by
\(a * b=a^3+b^3-3ab\)
For the operation to be commutative a*b should be equal to b*a.
Computing b*a:
\(b * a=b^3+a^3-3ba\)
Rearranging:
\(b * a=a^3+b^3-3ab\)
It's apparent that a*b=b*a, thus the operation is commutative

Suppose the supply and demand equations for a product are given by: p²+4q = 253 183 p² + 6q0 - Find the equilibrium point, and enter it as a point. Equilibrium Quantity: q = Equilibrium Price: p =
Answers
The equilibrium point for the supply and demand equations p² + 4q = 253 and 183p² + 6q = 0 is (q, p) = (3, 10).
To find the equilibrium point, we need to solve the system of equations formed by the supply and demand equations. By substituting the value of q = 3 into the first equation, we get p² + 4(3) = 253, which simplifies to p² + 12 = 253.
Solving this equation gives us p = 10. Substituting the values of q = 3 and p = 10 into the second equation, we get 183(10)² + 6(3) = 0, which simplifies to 18300 + 18 = 0.
Since this equation holds true, we have found the equilibrium point to be (q, p) = (3, 10), where the equilibrium quantity is q = 3 and the equilibrium price is p = 10.

Answers
The relative frequency of a class is computed by dividing the frequency of the class by the total number of observations in the data set. This statement (C) is true.
What is the relative frequency?
The relative frequency is a statistical term that represents the percentage of times a certain event occurs in an experiment or study. It is calculated by dividing the number of times an event occurred by the total number of trials in the experiment or study.
The class width is the difference between the upper limit and lower limit of a class. Class width is used to construct frequency histograms, cumulative frequency curves, and frequency polygons.The frequency of a class is the number of times the data falls within a certain class.
So, to compute the relative frequency of a class, divide the frequency of the class by the total number of observations in the data set. Therefore, option c, "dividing the frequency of the class by the total number of observations in the data set," is correct.

ulie went to visit her aunt and uncle for the weekend. she took the following clothes: two pairs of slacks – one brown, one black; three sweaters – one tan, one red and one white; two shirts – one white and one gray. what is the probability that julie will wear brown slacks and a white shirt? 23 16 112 14
Answers
The probability that Julie will wear brown slacks and a white shirt is 0.25.
To calculate the probability of Julie wearing brown slacks and a white shirt, we need to determine the total number of outfit combinations and the number of desired outcomes.
Julie has 2 options for slacks (brown or black) and 2 options for shirts (white or gray). Therefore, the total number of outfit combinations is 2 (slacks) multiplied by 2 (shirts) which equals 4.
Out of the 4 outfit combinations, Julie desires to wear brown slacks and a white shirt, which is only 1 combination.
To calculate the probability, we divide the number of desired outcomes by the total number of outfit combinations: 1 (desired outcome) divided by 4 (total combinations) equals 1/4.
In fraction form, the probability is 1/4. However, to convert it to decimal form, we divide 1 by 4, resulting in 0.25.
Therefore, the probability that Julie will wear brown slacks and a white shirt is 0.25.

a 5,645. 87 cm
b 7,234. 56 cm
c 1,113. 99 cm
Answers
The correct option is b. 7,234.56 cm.
To calculate the minimum storage space the container must have to fit all the balls, the formula for the volume of a sphere will be used.
Given the radius of each basketball is 12 cm, the volume of a sphere can be calculated as follows:V = 4/3πr³where;V is the volume of the sphereπ is the mathematical constant, pi. (3.1416) r is the radius of the sphere.
Substituting 12cm for r in the above formula, we get:\(V = 4/3π(12)³V = 4/3 x 3.1416 x 12³V = 7,238.23 cm³\)
Since there are 8 basketballs in the storage box, the total volume of the 8 basketballs is obtained by multiplying the volume of one basketball by 8.
Thus;Total volume = 7,238.23 cm³ x 8 = 57,905.84 cm³
Hence, the minimum amount of storage space the container must have to fit all the balls is 57,905.84 cm³.
