The lengths of three sides of a trapezoid are shown below:
side 1: 11z2 β 4z + 2
side 2: β2z + 3 + 12z2
side 3: 3 β 3z + 13z2
the perimeter of the trapezoid is 5z3 + 40z2 + 7z β 15.
part a: what is the total length of sides 1, 2, and 3, of the trapezoid?
part b: what is the length of the fourth side of the trapezoid?
part c: do the answers for part a and part b show that the polynomials are closed under addition and subtraction?
