Answer:

38

Explanation:

Don't worry this is pretty easy! Simply plug in your given values into the expression. So if a=3 and b=-5, we would put this in the equation.

8(3)-2(-5)+4

24+10+4<--- -2(-5) would be 10 since negatives cancel out. Remember to first to parentheses, then multiply/divide next.
