Answer:

4x+8y and 5(3x-y)

Explanation:

In the first question 4(x + 2y), you multiply 4 by both the x and the +2y. This is known as the distributive property. So, 4*x is 4x and 4(2y) is +8y. This is equal to 4x+8y.

In the second question 15x-5y, there is a common factor of 5, so you take 5 out and get 5(3x-y). If you open up these brackets, you get 15x-5y. This cannot be factored any further.
