Is there supposed to be a picture?? I see nothing im sorry. But i can help u cause this is just surface area, quite easy.
I will just give you the formula for surface area of a RECTANGULAR prism:
2 ( width x length + height x length + height x width) or just : 2 (wl + hl + hw)
Have a nice day
I think this is the answer to that,,, >y = 5x^2

First, solve the parentheses:

Next, the exponential terms

Solve the multiplication:

Add and subtract:
Answer:
length of each side of the room is 2√30 which is approximately 10.9545 ft
Explanation:
The area of the square can be computed as follows:
Area = l²
where l is the length of the side
We are given that:
area = 120 ft²
Substitute with the area in the above equation and solve for l as follows:
area = l²
120 = l²
l = √120
l = 2√30 ft
This is approximately equal to 10.9545 ft
Hope this helps :)
Answer:
3rd option
Step-by-step explanation:
Since the centre of dilatation is at the origin then multiply the coordinates by 
K (- 3, 9 ) → K' (- 3(
), 9(
) ) → K' (- 1, 3 )
L (- 9, 0 ) → L' (- 9(
), 0 (
) ) → L' (- 3, 0 )
M (2, - 8 ) → M' (2 (
), - 8 (
) ) → M' (
, -
)
N (6, 4 ) → N' (6 (
) , 4 (
) ) → N' ( 2,
)
