Which expression is equivalent to 16x +42y?

1- 7(2x+6y)

2- 6(3x+7y)

3- 2(8x+21y)

4- 4(4x+11y)

Answer 1

Find the Greatest Common Factor (GCF)

GCF = 2

Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2(16x/2 + 42y/2)

Simplify each term in parenthesis

C. 2(8x + 21y)
