Answer:
x > 35
Step-by-step explanation:
The perimeter is twice the sum of length and width. You want x such that ...
P > 156
2(x +(x+8)) > 156
4x +16 > 156 . . . . . simplify
x +4 > 39 . . . . . . . . divide by 4
x > 35 . . . . . . . . . . . subtract 4
The perimeter of the frame will be greater than 156 inches for x > 35.
