The ratio is 3:5.

You have to divide 72, so the sum of x and y is 72.

Set both expressions equal to each other:

72 divided in a ratio of 3:5 is
27:45.
256.
The coefficient of just the y term would be 256 because the entire expanded equation looks like this:
y^4+16y^3+96y^2+256y+256
The answer is 0, because you are adding an opposite to the original number, which always results in zero.
