We are provided that –

Applying identity –

\(\qquad\) \(\twoheadrightarrow\bf(w-10x) (w+10x)\)

\(\qquad\) \(\twoheadrightarrow\bf w^2 - (10x)^2\)

\(\qquad\) \(\twoheadrightarrow\bf w^2 -100 x^2\)

The result of the addition of fractions is given by:

D. \(-\frac{19}{x - 5}\)

The original expression is given by:

\(\frac{x^2 + 10x + 25}{x + 5} - \frac{x^2 - 6}{x - 5}\)

We consider the square of the sum notable product, given as follows:

(a + b)² = a² + 2ab + b².

Hence the following simplification can be applied:

Thus, we can simplify the expression as follows:

\(\frac{x^2 + 10x + 25}{x + 5} - \frac{x^2 - 6}{x - 5} = x + 5 - \frac{x^2 - 6}{x - 5}\)

Then, applying the least common factor of the denominator for the sum of the fractions, we have that:

\(x + 5 - \frac{x^2 - 6}{x - 5} = \frac{(x + 5)(x - 5) - x^2 + 6}{x - 5} = \frac{x^2 - 25 - x^2  + 6}{x - 5} = -\frac{19}{x - 5}\)

Hence the equivalent expression is:

As per the given statement, the quadratic equation is to be used to find the exact solutions to this equation, and the quadratic equation is given by \(ax² + bx + c = 0\).

To solve the quadratic equation, we can use the quadratic formula given by\(x = (-b ± sqrt(b² - 4ac)) / 2a\) Where x is the variable, a, b, and c are coefficients with a ≠ 0, and sqrt is the square root symbol.To find the exact solutions to this equation, we can use the quadratic formula with a = 2, b = 6, and c = 12.

Substituting these values in the quadratic formula, we get

\(x = (-6 ± sqrt(6² - 4 × 2 × 12)) / 2 × 2= (-6 ± sqrt(36 - 96)) / 4= (-6 ± sqrt(-60)) / 4= (-6 ± i√60) / 4= (-3 ± i√15) / 2\)

The equation's value of x is -50. To solve for x, we added 2 to both sides of -2/5x - 2 = 18. Then, we divided both sides by -2/5 or multiplied by -5/2 to get -2/5x = 20.

Answer: its -50

Step-by-step explanation:  the negatives cancel out. 50 divided by 5 is 10, so 1/5 of 50 is 10 and 2/5 of 50 is 20. then subtract 2.

To solve this question, we need to find the formula for the nth term of the geometric sequence. The formula is:

Where:

a_n is the nth term of the sequence

a_1 is the first term of the sequence

r is the common ratio

In this case:

a_1 8

r = 2/3

The answer is:

256/243

Answer:

Okay, let's break this down step-by-step:

   y varies directly with x, meaning y is proportional to x.

   This can be expressed as y = kx for some constant k.

   We are given: When x = 8, y = 104.

   Substituting the given values: 104 = k(8)

   Solving for k: k = 104/8 = 13

   Now we want to find y when x = 18. We use the proportional relationship:

   y = kx

   = 13(18)

   = 234

Therefore, when x = 18, y = 234.

Use the table in the book to find the P-value rounded to at least 4 decimal places.

It is not possible to find the exact P-value rounded to at least 4 decimal places by using tables, as the P-value is a continuous variable and tables only give a range of values containing the P-value.

The probability that you would have discovered a specific collection of observations if the null hypothesis were true is expressed as a number called the p value, which is determined from a statistical test.

In order to determine whether to reject the null hypothesis, P values are utilised in hypothesis testing. You are more inclined to reject the null hypothesis the smaller the p value.

The perimeter of triangle is 66.24 units.

What is triangle?

In Euclidean geometry, any 3 points, once non-collinear, verify a unique triangle and at the same time, a unique plane

Main body:

according to question :

c = 28

let the vertices be A,B,C

∠A= 30°

by using trigonometric ratios,

BC/ AB = sin30°

AB = C = 28

BC/28 = sin30°

BC = 28*sin30°

BC= 28*(1/2)

BC = 14

similarly

AB /CA = cos 30°

28/CA = √3/2

CA = 28*√3/2

CA = 14/√3

CA = 24.24

Hence , perimeter = AB +BC +CA = 28+14+24.24

Toni had 17 points, Effie had 25 points and Linda had 18 points.

The question is asking to find the number of points each girl had in a girl's basketball game. To find out how many points Effie had, you must multiply Toni's points by 3, subtract 8, and then multiply the difference by 2. To find out how many points Linda had, you must add 9 to Toni's points and divide the sum by 3. The given information is that Effie scored 9 more than Toni and Linda combined.

Formula and Calculation:

Toni's Points = x

Effie's Points = 3x-8

Linda's Points = (x+9)/3

Effie scored 9 more than Toni and Linda combined, so:

3x-8 = x+9/3 + 9

2x-8 = x+9

x = 17

Therefore, Toni had 17 points, Effie had 25 points and Linda had 18 points.

Step-by-step explanation:

Applying the triangle inequality theorem, the best representation for the third side is: A. 2 < s < 18.

According to the triangle inequality theorem, the sum of any two sides of a given triangle must be greater than the length of the measure of the third side of the triangle.

Thus, given an acute triangle has sides, 8 cm and 10 cm, applying the triangle inequality theorem, the range of sides would be calculated as shown below:

10 - 8 < s > 8 + 10

2 < s > 18

The range of values for the third side is: A. 2 < s < 18.

The total surface area of the new box is given by the equation:

SA_new = 2(LW + LH + 3.5L + WH + 3.5W + 7).

To calculate the new total surface area of the box after increasing the height by 3.5 centimeters, we need to consider the dimensions of the box and how each side is affected by the increase.

Let's assume the original box has dimensions:

Length (L)

Width (W)

Height (H)

The total surface area of the original box is given by:

SA_original = 2(LW + LH + WH)

After increasing the height by 3.5 centimeters, the new height becomes H + 3.5. The other dimensions, length and width, remain the same.

The new total surface area of the box can be calculated as follows:

SA_new = 2(LW + (L(H + 3.5)) + (W(H + 3.5)))

Simplifying the equation:

SA_new = 2(LW + LH + 3.5L + WH + 3.5W + 7)

Therefore, the total surface area of the new box is given by the equation:

SA_new = 2(LW + LH + 3.5L + WH + 3.5W + 7)

To find the closest value to the total surface area of the new box, you would need to know the specific values of L, W, and H for the original box. With those values, you can substitute them into the equation to calculate the exact surface area.

The probability that the artist chosen will be a painter or a photographer is 3/4

Probability is the function that measures the chances that an outcome of a random event will be as expected. In this way you can measure how likely it is that an event will happen.

To solve this exercise the formula and the procedure that we have to use for probability is:

probability= (achieving success / possible outcomes)

Achieving success = 7 painters + 5 photographer = 12

Possible outcomes = 7 painters + 5 photographer + 4 sculptors = 16

Applying the formula to calculate the probability we get:

probability= (achieving success / possible outcomes)

probability= 12/16

Simplifying:

probability= 3/4
