Yes, so if you know what b equals, you can put that number in for b around parenthesis.

We have **4b+8**, and know that **b = 8**, so that means

**4(8)+8** is our answer.

The parenthesis mean to multiply, so we multiply 4 times 8, and then add 8 to that.

**4 x 8 = 32**

add 8 to that

32+8 = **40**

40 is the answer.
