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?

Part B: What is the length of the fourth side of the quadrilateral?

Part C: Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer.
