it is hard and confusing

See Explanation

Explanation:

17:

it is saying a+b=b+a so put 5+16 that would be commutative

18:

if asking to rewrite it using the distributive prop do 20(2+x) that would still be distributive,

if asking to solve it is 40+2x

19: if I understand correctly it is asking you do write it using the associative property, if so do 4 * (60)

20: Do it as so, 6(x + 15) where x is your number

21: (x+5) + 27

22: 7(x+4) + 2x Simplify as so. Distribute, then add like terms (X)

7x + 28 + 2x

9X + 28

23: 6x + 15 - x + 4  Simplify : add and subtract like terms. (x) (#'s)

5x + 19.

24: 22y + 3x- 7y Simplify: Subtract like terms (y)

15y + 3x
