Answer 2

Ok, so the best thing to do here is to actually do the math. First, you want to do the multiplication, subtraction, and addition inside the parentheses. Remember PEMDAS: Parentheses, exponents, multiplication, division, addition, subtraction. That's the order you should do things in. After you've done everything in the parentheses, multiply those two values together. What do you get?

Is this clear enough? If not, I'll be happy to explain it further.

Answer 3

D?

Answer 4

Actually, quick question: I noticed that the answers include things such as 5x2. Is the "x" multiplication here, or a variable?
