Final answer:

To simplify the expression 3(6x + x), distribute the 3 to get 18x + 3x, which simplifies to 21x, corresponding to option (a).

Step-by-step explanation:

The student is asking to simplify the expression 3(6x + x). To simplify this expression, we distribute the 3 across the terms inside the parentheses:

3(6x) + 3(x) = 18x + 3x

Now, we combine like terms:

18x + 3x = 21x

Therefore, the simplified form of the expression 3(6x + x) is 21x, which corresponds to option (a).
