Answer:
C) 18 inches
Step-by-step explanation:
lets call the shortest side x.
that means the second side is 3x
the third side is x + 5
the perimeter of the triangle is 95 inches.
using this information, you can make the following equation:
x + 3x + x + 5 = 95
subtract 5 from both sides.
x + 3x + x = 90
5x = 90
x = 18
the shortest side is 18 inches long
