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.
