it is hard and confusing

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

pepin the short[a] (german: pippin der kurze, french: pépin le bref, c. 714 – 24 september 768) was the king of the franks from 751 until his death. he was the first of the carolingians to become king.[b][2]

the younger son of the frankish prince charles martel and his wife rotrude, pepin's upbringing was distinguished by the ecclesiastical education he had received from the monks of st. denis. succeeding his father as the mayor of the palace in 741, pepin reigned over francia jointly with his elder brother carloman. pepin ruled in neustria, burgundy, and provence, while his brother carloman established himself in austrasia, alemannia and thuringia. the brothers were active in suppressing revolts led by the bavarians, aquitanians, saxons, and the alemanni in the early years of their reign. in 743, they ended the frankish interregnum by choosing childeric iii, who was to be the last merovingian monarch, as figurehead king of the franks.
