Answer:
B. 11k + 16
Step-by-step 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
