Question

Combine like terms

7k + 4(k + 4)

A.8k + 16

B.11k + 16

C.7k + 1k + 16

D.27k

Answer 1

B. 11k + 16

Explanation:

We have an expression and are asked to combine like terms.

To solve this, we need to first distribute 4(k + 4). Which is to multiply four by both k and 4.

(4(k) + 4(4))

4k + 16

7k + 4k + 16.

Since 7k and 4k are like terms since they end in the same variable, we can only add them.

7 + 4

11

11k + 16
