Step-by-step explanation:

Hello!

A)

The area of a rectangle is L * W.

  • Area = (6x + 4)(2x + 11)
  • Area = 12x² + 8x + 66x + 44
  • Area = 12x² + 74x + 44

B)

The degree of a polynomial is the value of the highest exponent. The degree of 12x² + 74x + 44 is 2, because 2 is the highest exponent.

C)

This demonstrates the closure property, as adding, subtracting, and or multiplying polynomials will give a polynomial.
