GCF Factoring Linear

A sidewalk has an area that can be represented by the expression (8x + 24) feet. What are the possible dimensions of the sidewalk? Select all correct answers.

• 8(x + 3)

• 4(2x + 6)

• 2(4x + 12)

• 1(8x + 24)

What are the possible dimensions of the garden?

• 4x + 36

• 4(x + 9)

• 2x(2 + 18)

• 4x(1 + 9)

Enrique is factoring the expression 90x - 15. He writes: 90x - 15 = 15(6x) 15(6x) = 90x Find his mistake and correct it.

• There is no error.

• The GCF is 5, so the final expression should be 5(18x - 3)

• This expression cannot be factored because there is no GCF.

• The expression should read: 15(6x - 1)

Factor -3x - 30

• -3(x + 10)

• -3(x - 10)

• 3(x - 10)

• 3(x + 10)

Factor 25x + 45 using the GCF.

• x(25 + 45)

• 5(5x + 9)

• 25(x + 2)

• 5(5x + 45)

Which of the following cannot be factored?

• 6 + 3x

• 7x + 3

• 15x + 10

• 30x + 40
