The perimeter of a triangle is 45 centimeters. Find the lengths of its sides, if the longest side is 7 centimeters longer than the shortest side, and the remaining side is 2 centimeters longer than the shortest side.

  1. Reiny

    Just translate into math:

    shortest side --- x
    longest side ---- x+7
    remaining side --- x+2

    solve:
    x + x+7 + x+2 = 45
