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.
Just translate into math:
shortest side --- x
longest side ---- x+7
remaining side --- x+2
x + x+7 + x+2 = 45posted by Reiny
