    The lengths of two sides of a triangle are shown below: Side 1: 5x2 + 2x - 3 Side 2: 8x - 3x2 + 2 The perimeter of the triangle is 2x3 - 5x2 + 4x - 8. Part A: What is the total length of the two sides, 1 and 2, of the triangle? (4 points) Part B: What is the length of the third side of the triangle? (4 points) Part C: Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer. (2 points)

    Perimeter of a triangle (P) = A + B + C A = 5x2 + 2x - 3 B = 8x - 3x2 + 2 C = ? P = 2x3 - 5x2 + 4x - 8

    demonstrated by the fact when you combine the side 1, side 2 and the result of side 3 you get the given perimeter
