Answer:

6x + 12y

Step-by-step explanation:

Using distributive property means multiplying the number outside of the parentheses to each individual number within the parentheses:

3 × 2x = 6x

3 × 4y = 12y

Since there is an addition sign within the parentheses, we add these two numbers together. However, they are not like terms so their sum cannot actually be calculated

6x + 12y
