Answer:

x+7

Step-by-step explanation:

If x is always greater than -7, then the value of the equation will always be positive, rendering the absolute value bars obsolete. Observe:

If x = -6, -6 + 7 = 1. With or without absolute value, this equals 1.

If x = 2, 2 + 7 = 9.

If x = 9, 9 + 7 = 16.

And so on and so forth.

I'm assuming side length is the variable S, so you do 16 squared (256) times 6 (1,536) As your final answer. This may be wrong, as I may be interpreting wrong.
