the perimeter of this hexagon is 162 cm. each longer side measures 1cm more than twice a shorter side. find the length of the side labeled x.

  • math -

    side1 = x
    side2 = 2x+1
    side3 = 2(2x+1) + 1 = 4x + 3
    side4 = 2(4x+3) + 1 = 8x + 7
    side5 = 2(8x+7) + 1 = 16x + 15
    side5 = 32x + 31

    add them up = 162
    solve for x
