Given in the question
\(\text{Area}_{RECTANGLE}=54in^2\)The length of the rectangle is
\(l=3(n-1)=3n-3\)The breadth of the rectangle is
\(b=n+2\)The formula for the Area of a rectangle is
\(\begin{gathered} \text{Area}_{RECTANGLE}=\text{length}\times breadth \\ \text{Area}_{RECTANGLE}=l\times b \end{gathered}\)By substituting the values, we will have
\(\begin{gathered} \text{Area}_{RECTANGLE}=(3n-3)\times(n+2) \\ (3n-3)\times(n+2)=54 \end{gathered}\)By expanding the brackets, we will have
\(\begin{gathered} (3n-3)\times(n+2)=54 \\ 3n(n+2)-3(n+2)=54 \\ 3n^2+6n-3n-6=54 \\ 3n^2+3n-6-54=0 \\ 3n^2+3n-60=0 \end{gathered}\)Therefore,
The final answer is = 3n² + 3n - 60 = 0

A quadratic equation, y = ax^2 - 6x + 10, has exactly one real root. Calculate the value of a.
Answer:
a = 0.9
Step-by-step explanation:
For the quadratic equation \(\boxed{ax^2 + bx + c = 0}\) to have exactly one real root, the value of its discriminant, \(\boxed{b^2 - 4ac}\), must be zero.
For the given equation:
\(y = ax^2 - 6x + 10\),
• a = a
• b = -6
• c = 10.
Substituting these values into the formula for discriminant, we get:
\((-6)^2 - 4(a)(10) = 0\)
⇒ \(36 - 40a = 0\)
⇒ \(36 = 40a\)
⇒ \(a = \frac{36}{40}\)
⇒ \(a = \bf 0.9\)
Therefore the value of a is 0.9 when the given quadratic has exactly one root.
The population of a town is predicted to grow according to the following model:

O 16,912 people
O 16,913 people
O 16 people
O 17 people
The predicted population in the year 2030 is 10 people
How to determine the predicted population in the year 2030From the question, we have the following parameters that can be used in our computation:
Population function, P(t)= 15е⁻⁰.⁰¹²⁺
Also from the question, we have
The variable t represents the number of years since 2020
This means that the value of t in 2030 is
t = 2030 - 2020
t = 10
So, we have
P(10)= 15е⁻⁰.⁰¹² ˣ ¹⁰
Evaluate the above products
P(10)= 15е⁻⁰.¹²
Evaluate the exponents
P(10)= 13.30
Approximate the above expression
P(10) = 13
This means that the number of people is 13

Consider the curve given by the equation x2 − y2 = 2x + y + xy − 4. Find the equation
of the tangent line to the curve at the point (1, 1).
The equation of the tangent line at (1,1) is given as follows:
y - 1 = -0.25(x - 1).
How to obtain the equation of the tangent line?The curve for this problem is given as follows:
x² - y² = 2x + y + xy - 4.
Applying implicit differentiation, we obtain the slope of the tangent line, as follows:
2x - 2y(dy/dx) = 2 + (dy/dx) + x(dy/dx) + y
(dy/dx)(1 + x + 2y) = 2x - 2 - y
m = (2x - 2 - y)/(1 + x + 2y).
At x = 1 and y = 1, the slope is given as follows:
m = (2 - 2 - 1)/(1 + 1 + 2)
m = -0.25.
Hence the point-slope equation is given as follows:
y - 1 = -0.25(x - 1).

Becky and Lewis's hamster cages have the same perimeter. Lewis's cage has a length 0.75 times the length of Becky's cage. What is the width, w, of Lewis’s cage?
On applying the formula of perimeter the width of Lewis's cage is obtained as 14.86 inches.
What is perimeter?
The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.
Mathematically, the perimeter of a rectangle can be calculated by using this formula -
P = 2(L + W)
Where -
P represents the perimeter of a rectangle.
L represents the length of a rectangle.
W represents the width of a rectangle.
For the perimeter of Becky's rectangular cage, calculate the value -
Perimeter, P = 2(L + W)
Substituting the values and solving the equation -
Perimeter, P = 2(15 + 11)
Perimeter, P = 2(26)
Perimeter, P = 52 inches.
For the perimeter of Lewis's rectangular cage, the value given is -
Length of Lewis's rectangular cage is 0.75 times the length of Becky's cage.
L = 0.75W
The value for perimeter will be -
Perimeter, P = 2(L + W)
Solving the equation -
52 = 2(0.75W + W)
26 = (0.75W + W)
1.75W = 26
Width, W = 26/1.75
Width, W = 14.86 inches.
Therefore. the value for width is obtained as 14.86 inches.

A shop had a sale on t shirts. For every two shirts purchased on regular price a third t shirts was bought for shs 100 .twelve t shirts for shs 12000.what was the regular price in shs for one shirt
According to the given information, the regular price of a single T-shirt is shs 100.
What is the rate?The problem statement does not provide enough information to determine the rate of return or interest rate. In the absence of this information, it is not possible to calculate the rate of return or interest rate earned on the capital contributions or on the profit made by the company.
According to the given information:Let's assume that the regular price of a single T-shirt is x shillings.
During the sale, for every two T-shirts purchased at the regular price, a third T-shirt was bought for shs 100. This means that three T-shirts were sold for the price of two T-shirts plus shs 100, or:
2x + 100 = 3(x)
Simplifying and solving for x, we get:
x = 100
So the regular price of a single T-shirt is shs 100.
Now, we're told that twelve T-shirts were sold for shs 12,000. If we assume that all of these T-shirts were purchased during the sale, then 8 of the T-shirts were purchased at the regular price and 4 of the T-shirts were purchased for shs 100 each.
So the total amount spent on the 8 T-shirts purchased at the regular price is:
8x = 8 * 100 = shs 800
And the total amount spent on the 4 T-shirts purchased for shs 100 each is:
4 * 100 = shs 400
Therefore, the total amount spent on all 12 T-shirts is:
shs 800 + shs 400 = shs 1,200
This matches the total amount mentioned in the problem statement, which means that our assumption that all of the T-shirts were purchased during the sale is correct.
Therefore, according to the given information, the regular price of a single T-shirt is shs 100.

a quadratic function with a constant difference of 2
an exponential function with growth factors of 1, then 2, then 4, ..
The best description of the graph is "a quadratic function with a constant difference of 2."
A quadratic function is a function of the form f(x) = ax^2 + bx + c, where a, b, and c are constants. In a quadratic function, the graph forms a parabola.
In the given graph, if the differences between consecutive points on the graph are constant and equal to 2, it indicates a constant difference in the y-values (vertical direction) as the x-values (horizontal direction) increase. This is a characteristic of a quadratic function.
On the other hand, an exponential function with a growth factor of 2 would result in a graph that increases at an increasing rate, where the y-values grow exponentially as the x-values increase. This is not observed in the given graph.
Therefore, based on the information provided, the graph best represents a quadratic function with a constant difference of 2.

In 2021 a 30-second commercial during the Super Bowl cost $5.6 million and the CPI was approximately 271.4. Assuming that price changes are simply due to inflation, what would the same 30 second commercial have cost during the first Super Bowl in 1967, when the CPI was 33.4? Round your answer to the nearest hundred dollars.
In 2021 a 30-second commercial during the Super Bowl cost $5.6 million and the CPI was approximately 271.4. Assuming that price changes are simply due to inflation, when the CPI was 33.4 the estimated cost of a 30-second commercial during the first Super Bowl in 1967 would be approximately $68,900.
To calculate the cost of the 30-second commercial during the first Super Bowl in 1967, we can use the concept of inflation and the Consumer Price Index (CPI).
The CPI measures the average price change of a basket of goods and services over time. By comparing the CPI values of two different years, we can estimate the relative increase in prices due to inflation.
Given data:
Cost of a 30-second commercial in 2021 = $5.6 million
CPI in 2021 = 271.4
CPI in 1967 = 33.4
To calculate the cost in 1967, we need to adjust the 2021 cost for inflation using the CPI ratio:
Cost in 1967 = (Cost in 2021) * (CPI in 1967 / CPI in 2021)
Cost in 1967 = ($5.6 million) * (33.4 / 271.4)
Cost in 1967 ≈ $0.689 million
To round the cost to the nearest hundred dollars, we can multiply the cost by 100 and round it to the nearest whole number:
Cost in 1967 ≈ $68,900

A finite set of equations for which common solutions are sought is referred to as a set of simultaneous equations, often known as a system of equations or an equation system.
Here, we have
Given: There was a total of 20800 sacks of rice in Factory A and Factory B.
Let us assume
The sacks in factory A = x
and the sacks in factory B = y
∴ x + y = 20800
y = 20800 - x
After of 3/4, the sacks of rice in Factory A and 3/5 of the sacks of rice in Factory B were sold.
∴ 3x/4 + 3y/5 were sold
x -3x/4 + y - 3y/5 = x + 1040 + x
x -3x/4 + 20800 - x -3/5(20800 - x) = 2x + 1040
