the lengths of two sides of a triangle are shown.
side 1: 8x2 − 5x − 2
side 2: 7x − x2 + 3
the perimeter of the triangle is 4x3 − 3x2 + 2x − 6.
part a: what is the total length of the two sides, 1 and 2, of the triangle? show your work.
part b: what is the length of the third side of the triangle? show your work.
part c: do the answers for part a and part b show that the polynomials are closed under addition and subtraction? justify your answer.
