Answer:

2b + 2c

Step-by-step explanation:

If you distribute the 2 in b and c you will get to separate terms that will be added together. Since they are not like terms they cannot be combined.

The distributive property means you just multiply the outside number by the terms in the parenthesis. So 2 * b and 2 * c

2(b + c)\\2(b + 2c)
