mhanifa · Answer

Part A.
Area = w*l, substitute w = 6x + 4, l = 2x + 11 and find the expression
Part B.
Since each of the multiples are of degree one, the resultant expression will have the degree of 1 + 1. Name the polynomial as you get the result of Part A
Lets discuss part C once you complete parts A and B
