Question

Four expressions are shown:

A. 10x + 6

B. 12x + 4

C. 2(5x + 3)

D. 2(6x + 2)

Which two expressions are equivalent to 2(5x + 2 + x)? (1 point)

A and C

B and D

A and D

B and C

Answer 1

B and D

Explanation:

Simplify the given expression as shown below:

• 2(5x+2+x)

= 2(6x+2) = D

Also

• 2(6x+2) = (2×6x) + (2×2)

= 12x + 4 = B

Hence Both B and D are equivalent to 2(5x+2+x)
