Question

use the properties of operations to write three different equivalent expressions to represent the lengths of the other three sides of the square.one of your expressions should create two terms

Answer 1

It had been highlighted in the problem that the shape is indeed a square. Thus, we have for sides equal, since we are given with an expression for the first side, we can easily solve for the remaining sides such as below:
1st side=6(3X+8) + 32 +12X
2nd side=18X+48 +32+12X
3rd side=18x+80+12x
4th side=30x+80
