The lengths of two sides of a triangle are shown.
Side 1: 8x^2 − 5x − 2
Side 2: 7x − x^2 + 3
The perimeter of the triangle is 4x^3 − 3x^2 + 2x − 6.
Part A: What is the total length of the two sides, 1 and 2, of the triangle? Show your work. (4 points)
Part B: What is the length of the third side of the triangle? Show your work. (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)
