Answer:
3ac + bc
Explanation:
Distributive property mean you "distribute" the term outside the parenthesis to both terms inside the parentheses. What that means is you multiply the outside term by both of the terms on the inside.
c(3a + b) becomes (c)(3a) + (c)(b) which simplifies to 3ac + bc
*Variables are written in alphabetical order if they are all to the first power, like these are. We can rearrange them like this because order multiplication doesn't matter. (2)(3) = (3)(2)
