The lengths of two sides of a triangle are shown.
Side 1: 3x^2− 2x − 1
Side 2: 9x + 2x^2− 3
The perimeter of the triangle is 5x^3+ 4x^2 − x − 3.
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)
