Question

The length of a picture frame is inches more than the width. For what values of x is the perimeter of the picture frame greater than ​inches?

Answer 1

9514 1404 393

Answer:

x > 35

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.
