Question 26209: The first side of a triangle is 8 meters longer than twice the second side. The third side is 3 times the second side. The perimeter is 128 meters. Find the lengths of the three sides. Answer by uknouluvme89(30) (Show Source):
You can put this solution on YOUR website! Let x = second side
Let 2x+8 = first side
Let 3x = third side
the perimeter is the addition of all three sides so:
x+2x+8+3x = 128
add the like terms:
6x+8 = 128
subtract 8 from both sides of the equation:
6x=120
divide both sides by 6 to get:
x=20
Hope you understand!
