Answer:
9
Explanation:
First you put in b, which would look like this: 4(1/4+2)
Then you could do it two ways, you can use distributive property, or just add within the parenthisis.
Distributive Property:
it would be 4* 1/4, which is one, and add 4*2, which is nine.
Parenthesis:
just add 2 and 1/4, which is 2 1/4. 2 1/4 is equal to 9/4, and that times 4 is nine.
Hope it helps!
