18. A flower-bed is in the shape of a triangle with one side twice the length of the
shortest side and the third side 15 feet longer than the shortest side. If the perimeter
is 100 feet and if x represents the length of the shortest side, find an equation to
solve for the lengths of the three sides.

B)
x + 15 = 2x
C)
x + 15 + 2x = 100
D)
x + 2x = x + 115
