• 3x²+16x-5

• 3x²-14x+5

• 3x²-14x-5

What is the Area?

Choose the correct answer below.

The total area of the playground, the larger rectangle, is 
16x² − 5x + 2. The area of the play area, the smaller rectangle, is 10x² + 3x − 1. Write an expression to represent the area of the sidewalk.

• 6x² − 8x + 3

• 16x² − 8x + 3

• 16x² − 2x + 1

What is the Area?

• 2x² - 3x - 18 inches²

• 2x² + 3x + 18 inches²

• 2x² + 9x - 18 inches²

• 2x² - 9x - 18 inches²

A rectangular garden has a length of 2x - 7 and a width of 3x. Write a simplified expression to represent the area of the garden.

• 6x² + 21x

• 6x² - 21

• 6x²- 21x

• 5x² + 21x

Which expression represents the simplified area of the rectangle?

• x² + 9x + 20

• x² + 9x - 20

• x² + x - 20

• x² - x - 20

Which expression is the simplified area of a rectangle with a length of (3$ – 1) and a width of ($ + 5)?

• 3$² + 4$ + 5

• 3$² + 4$ - 5
