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
