The answer is pretty simple. This is all that you do. You would multiply 2 times s. Then you would multiply 2 times 9. Do you get it? For number 14 all you would do is: -10 times -9 times -5. This is 450. On the last one, fill in the a for a and b for b.
3 times -5 minus 4 times 2.
this would be: -15 minus 8
Do you get it now?

13. 2s + 18.
14. -10 * -9 =90 * -5 = -450
15. Plug in: 3(-5) - 4(2) --> -15 - 8 = -23
Hope I helped! :)
