Answer:

21x + 35y

Step-by-step explanation:

When doing these expression problems, you have to DISTRIBUTE

When distributing, you multiply the 7 on the OUTSIDE of the parentheses to the 3x and if you know 7x3 is 21 so it becomes 21x

Now we do the same thing to the 5y, we multiply the 7 by the 5y to get 35y

Since we can’t combine the terms since they have different variables, our final answer is 21x + 35y

Hope this helps and please award brainliest!
