Algebraic expression

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.

if a letter representing a number is next to a number, you multiply
