Worth 30 a rectangle has sides measuring (6x + 4) units and (2x + 11) units. part a: what is the expression that represents the area of the rectangle? show your work to receive full credit. part b: what are the degree and classification of the expression obtained in part a? part c: how does part a demonstrate the closure property for polynomials?

Part a: what is the expression that represents the area of the rectangle? show your work to receive full credit.  a = l * wa =  (6x + 4) (2x + 11)  a = 12x^2 + 8x + 66x + 44a = 12x^2 + 74x + 44part b: what are the degree and classification of the expression obtained in part a?   from part a, a = 12x^2 + 74x + 44  the expression is the second degree so it is classified as a second polynomial.part c: how does part a demonstrate the closure property for polynomials? the closure property for this  polynomials is under multiplication
