    Answer:

    s = 2x²+3x-23

    Step-by-step explanation:

    Given that,

    First side of a triangle = 3x+8

    Second side of a triangle = 2x²-4x+5

    The perimeter of the triangle = 4x²+2x-10

    We need to find the expression for the third side. Let the third side b s.

    Perimeter = Sum of all sides

    4x²+2x-10 = 3x+8 + 2x²-4x+5 +s

    4x²+2x-10 = 2x²-x+13+s

    s = 4x²+2x-10- (2x²-x+13)

    = 2x²+3x-23

    So, the third side will be 2x²+3x-23.
