Select all of the pairs of expressions that are equivalent.

E 4j + 6k and 2(2j + 3k)

Answer 1

A

B

E

Explanation:

For A, we can simplify it to 2c + 2d by combining like terms. We can then factor out 2 and get 2(c + d).

For B, we combine like terms and 7y - x. We can move the x in front and get -x + 7y.

For E we can factor out 2 and get 2(2j + 3k).

Hope this helps
