A rectangle is x+4 long and x wide. Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less than 112.
perimeter of a rectangle = length + length + width + width
length + length + width + width = perimeter of a rectangle
(x +4) + (x+4) + x + x < 112
x + 4 + x + 4 + x + x < 112
4x + 8 < 112
4x < 104
x < 26
