    the longest side is 25

    Step-by-step explanation:

    the equation would be x + x+1 + 7 for the 3 sides of the triangle

    x + (x+1) + 7=56

    combine like terms

    2x+8 = 56

    subtract 8 from each side

    2x = 48

    divide by 2

    x = 24

    the sides are

    x=24

    x+1 = 25

    7

    the longest side is 25
