Answer:
15 :D
Step-by-step explanation:
Well, we know b = 3 so we can rewrite the expression to make it less confusing. So, we change b for 3, which is the same thing but number form:
2(3) + 9
Now we evaluate 2(3) which would be 2 x 3. 2 x 3 is 6, so we rewrite 2(3) as 6.
6 + 9
and finally, 6 + 9 is 15!
