Andrew is creating a rectangular dog run in his back yard. The length of the dog run is 16 feet. The perimeter of the dog run must be at least 38 feet and no more than 64 feet. Use a compound inequality to find the range of values for the width of the dog run. Use
x
when writing your inequality.
width of run ---- x ft
perimeter = 2(16+x)
38 ≤ 2(16+x) ≤ 64
divide by 2
19 ≤ 16+x ≤ 32
subtract 16
3 ≤ x < 16
