Answer:

3x+36

2x+5

Step-by-step explanation:

The length is (x+12) and the width is 3

A = l*w

A = (x+12)*3

Distribute

3x+36

Answer:

3x + 36 for the first question and 2x + 5 for the second question

Step-by-step explanation:

For the first question, you have to calculate the area of the two rectangles separately and then add them together.

3 · x = 3x

3 · 12 = 36

Add your results together and you get 3x + 36

For the second question, we know Elliot has made 5 dollars more than 2 times how much Bruce has made. Bruce has earned x dollars and we are trying to find out how much Elliot earned.

2 times how much Bruce has made can be represented as 2 · x = 2x

Elliot has made 5 dollars more than 2 times how much Bruce has made so you add 5 to your answer

Elliot has made 2x + 5 dollars

2^4n × 2^ 2n = 512 What is the value of n.

Marina86 [1]

Step-by-step explanation:

${2}^{4n} \times {2}^{2n} = 512$

${2}^{4n} \times {2}^{2n} = {2}^{9}$

${2}^{4n + 2n} = {2}^{9}$

$6n = 9$

$n = \frac{3}{2}$

High-power experimental engines are being developed by the Stevens Motor Company for use in its new sports coupe. The engineers

Maurinko [17]

Answer:

The 99% of a confidence interval for the average maximum HP for the experimental engine.

(536.46, 603.54)

Step-by-step explanation:

Step:-1

Given that the mean of the Population = 540HP

Given that the size of the sample 'n' = 9

Given that the mean of the sample = 570HP

Given that the sample standard deviation = 30HP

Step(ii):-

Degrees of freedom = n-1 =9-1 =8

t₀.₀₀₅ = 3.3554

The 99% of a confidence interval for the average maximum HP for the experimental engine.

$(x^{-} - t_{\frac{0.01}{2} ,8} \frac{S.D}{\sqrt{n} } ,x^{2} + t_{\frac{0.01}{2},8 } \frac{S.D}{\sqrt{n} } )$

$(570-3.354\frac{30}{\sqrt{9} } , 570+3.354\frac{30}{\sqrt{9} } )$

(570 - 33.54 , 570+33.54)

(536.46 , 603.54)

Final answer :-

The 99% of a confidence interval for the average maximum HP for the experimental engine.
