1. Warm-Up Your neighbor asks you to cut her lawn. Her lawn is (6x+3) feet wide and (10x+3) feet long. A section of the lawn is covered by a small shed. The shed is (x-2) ft wide and (x+2) ft long. Write a polynomial that represents the total area of the lawn. Write a polynomial that represents the total area of the shed. Write a polynomial that represents the area of the lawn that you will mow.

2. Warm-Up Perform the indicated operation Put in standard form and classify (3n – 4n 2 + 7) +(7n 2 + 5n – 6) (7y 3 + 4y 2 -5y +3) – (8y 3 – 4y 2 -2y + 2) -3t 2 (3t 2 – 4t + 5) (x+3)(x-2)
