Answer 1

6. 9 + 11y – y2 + y3 – 4y4
This expression has 5 terms.

7. (2a + 3b) + 4c = 2a + (3b + 4c)
Associative property of addition, because you're moving the parentheses.

8. If m = 4 and n = 4, then m = n
Substitution property.

9. -9 + 5 – (-2) + 17
-4 - (-2) + 17
-2 + 17
15

10. - 35 - (- 13 )
-22

11. -40 + 23 - 19 + 31
-17 - 19 + 21
36 + 21
57

12. (-2)³
-2 * -2 * -2
-8

13. - 925

14. 15(3y – 5)
45y - 75

15. (7 + 6w)6
42 + 36w

16. 3n+57
