Hi everybody!

I need help on an Algebra 1 question.

35 points for help.

The length of a rectangle is (5x2 + 4x - 4) units, and its width is (4x3 - 2x + 6) units.

Part A: What is the area of the rectangle? Show your work.

Part B: Does the answer for Part A show that polynomials are closed under an operation? Justify your answer.

Part C: What is the degree and classification of the expression obtained in Part A?

Thank you!
