Question 1143870: In a triangle, one side is twice the smallest side. The third side is 2 less than 3 times the smallest side. The perimeter is 40 inches. Find the three side lengths of the triangle. Answer by ikleyn(52890) (Show Source):
Let x be the shortest side length. Then the two other sides are 2x and 3x-2 units long.
The perimeter is x + 2x + (3x-2).
The equation is
x + 2x + (3x-2) = 40 inches.
Simplify and solve for x.
