Answer:
(2x+3) y (3x+5)
Step-by-step explanation:
For this exercise we have that the volume is
V = 6x ^ 3 + 31X ^ 2 + 53x + 30
H = X + 2
The formula for the Volume its
V = H * L * W
for find L and W (width and length) we divide V / H = L * W
So,

this division is in the attachment
so, L * W = (2x + 3) * (3x + 5)
I believe it would be under 8 percent since 9 is lower
Yes you use the method of your choice to solve (x+7)*(x+7)
Then you distribute the negative -1(x^2+14x+49)
Then you add the four
-x^2-14x-45 should be your answer
Sorry im a little late but here's how i did it.
Hope this helps! :)
