The lengths of three sides of a quadrilateral are shown below:
side 1: 3y2 + 2y − 6
side 2: 3y − 7 + 4y2
side 3: −8 + 5y2 + 4y
the perimeter of the quadrilateral is 4y3 + 18y2 + 16y − 26.
part a: what is the total length of sides 1, 2, and 3 of the quadrilateral? (4 points)
part b: what is the length of the fourth side of the quadrilateral? (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)
