Can you double check my answer

The lengths of the sides of a rectangular window have the ratio 1.6 to 1. The area of the window is 2,560 square inches. What are the dimensions of the window? (1 point)

50.6 inches by 50.6 inches
40 inches by 64 inches
40 inches by 80 inches <------ my answer
40 inches by 102.4 inches

this was of zero help😐 you cant even cheat these days🙄🤚🏾

A = Area

W = Width

L = Length

L = 1.6 W

A = L * W

A = 1.6 W * W

A = 1.6 W ^ 2

2,560 = 1.6 W ^ 2 Diwide both sides by 1.6

2,560 / 1.6 = W ^ 2

1600 = W ^ 2

W = sqrt ( 1600 ) = 40 in

L = 1.6 * 40 = 64 in

Answer:

40 in by 64 in

it's correct bro

I am SUPERIOR

thx bruh

any number in the form of a+-bi where a and b are real numbers and b =/ 0 is considered a pure imaginary number

False

the minimum value of a function is the smallest y- value of a function

True

i^2 = square root -1

False

complex numbers can be graphed on the real xy coordinate plane

False

To double-check your answer, we can calculate the dimensions of the window using the given information.

We know that the lengths of the sides of the rectangular window have a ratio of 1.6 to 1. Let's assume the length of the shorter side is x inches. Therefore, the length of the longer side would be 1.6x inches.

We are also given that the area of the window is 2,560 square inches. The formula to calculate the area of a rectangle is length multiplied by width, which in this case would be x * 1.6x = 2,560.

Let's solve this equation to find the value of x:

x * 1.6x = 2,560
1.6x^2 = 2,560
x^2 = 2,560 / 1.6
x^2 = 1,600
x = √1,600
x = 40

Now that we have the value of x, we can find the dimensions of the window:

Shorter side: x = 40 inches
Longer side: 1.6x = 1.6 * 40 = 64 inches

Therefore, the correct dimensions of the window are 40 inches by 64 inches.
