The lengths of two sides of a triangle are shown below:
side 1: 3x2 β 2x β 1
side 2: 9x + 2x2 β 3
the perimeter of the triangle is 5x3 + 4x2 β x β 3.
part a: what is the total length of the two sides, 1 and 2, of the triangle? (5 points)
part b: what is the length of the third side of the triangle(hint: take the total perimeter and subtact off the total lenght of the other 2 sides found in part a)?
part c: do the answers for part a and part b show that the polynomials are closed under addition and subtraction? justify your answer.
