Answer:
36 + 14b
Explanation:
You have to use the distributive property for the 7(4+2b) part, by multiplying 7 with 4 and 2b. Which equals 28 + 14b, but you can't forget the 8, and you can't combine whole numbers with numbers with a variable attached to it. So it would be 8 + 28 + 14b, and you combine like terms, making the answer 36 + 14b
