Answer:

21x

Explanation:

7x is one term. With parenthesis, you have to multiply whatever is on the outside, inside. So that's 3*7x, or 21x.

Hope this helps!

Hey there!

3(7x)

= 3 * 7x

= 7x * 3

= 7x + 7x + 7x

= 14x + 7x

= 21x


Therefore, the answer should be: 21x


Good luck on your assignment & enjoy your day!
