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.

  • Pre Algebra - ,

    Let x = second side

    First side = 2x +8

    Third side = 3x

    x + (2x + 8) + 3x = 128

    Solve for x, then the other sides.

    I hope this helps.
