Answer:
6a+4b-14
Step-by-step explanation:
For this, we have to use the distributive property.
This means we multiply each value in the parentheses by 2.
2*3a=6a
2*2b=4b
2*(-7)=-14
So our equation is:
6a+4b-14
(13 + 14) + 11 = 13 + (14 + 11) --- associative property
13 + 14 + 11 = 11 + 14 + 13 -- commutative property
