one side of a triangle is 2cm shorter than the base The ofther side is 3cm longer than the base what lengths of the base will allow the perimeter to be greater than 19 cm?

  • algebra 1 -

    let base be x
    one other side = x-2
    third side = x+3

    x + x-2 + x+3 > 19
    3x > 18
    x > 6

    test: let base be 7
    one other side = 5
    third side = 10
    perm = 22
