What polynomial represents the perimeter for the given rectangle? Use the formula on your formula sheet.

• 6x³ - 9x² + 10x - 15
• 6x² + 1x - 15
• 6x² + 4x + 4
• 6x³ + 1x² - 15x

Which expression represents the simplified area of the rectangle? Use the formula on your formula sheet.

• x² + 9x + 20

• x² + 9x - 20

• x² + x - 20

• x² - x - 20

Jen has a square bedroom with dimensions x by x. She decides to renovate her room. If she makes the length 4 feet longer but decreases the width by 2 feet, what are the new dimensions (the length and width) of her new room?

• Length (x-4)

  Width (x+2)

• Length 4x

  Width 2x

• Length (x+4)

  Width (x+2)

• Length: (x+4)

  width: (x-2)

Suppose Jen did not like the new room, so instead she altered her plans so that the length is increased by 5 and the width is decreased by one. Then her NEW length will be (x+5) and her NEW width will be (x-1). Which expression represents the area of her new room?
