Answer:
Is a. 5b+40
Step-by-step explanation:
The distributive property explains that the multiplication of a number by a sum is equal to the multiplication of the number by each of the addends. So in this case we can multiply the number 5 by each one of the addends, this is:
\(5*(b+8)=5*b+5*8=5b+40\)
From the above the answer is a. 5b+40
