find the lengths of the sides of a triangle whose perimeter is 37. The measure of the first side of the triangle is 8 less than the second side, and the second side is twice the length of the third side

3 answers

third side --- x
second --- 2x
first---- 2x - 8

can you solve
x + 2x + 2x-8 = 37 ?
x=9
If the perimeter of the first triangle is 21 m, what is the perimeter of the second?
