Use the GCF(greatest common factor) to factor this expression

12x + 48y - 24

• 24(x + 2y)

• 6(2x + 8y - 4)

• 12(x + 4y - 2)

• 4(3x + 12y - 6)

Evaluate the following expression when a = 4, c = 2 and g = 3

1.59a + 2.29c + 0.79g

• 15.21

• 13.31

• 14.15

Simplify the expression:

4(8) +3(x - 6)

• 4x - 42

• 24 + 3x

• 7x + 24

• 3x +14

Simplify the expression:

-7b + 10c + 9 - 13b - 4c + 13

• -27b + 16c + 22

• -17b + 6c + 22

• -20b + 6c + 22

• -7b + 14c - 4

Factor the following expression:

-20x + 6y + 22

• 2(-10x + 3y + 11)

• 5(-4x + 2y + 11)

• 7(-3x + 2y + 4)

• 10(-2x + y + 22)

• -7x - 4

• -7x - 3

Simplify this expression:

-9w + (-12) + 9 + (- 8w)

• -17w + 9

• -17w - 3

• -25w + 9

• x + 6y - 21

• 3x + 12y -11

• 9x + 5y - 4
