Question

Can someone help me with questions 25 through 28

Answer 1

25. 3y+15

26. 15k+20

27. 21n+7p

28. 60w+20x

Also, you got number 19, number 21, and number 24 wrong.

D+D+D+D+D = 5D, not D⁵

S+S+S = 3S, not S³

N+N+N+N = 4N, not N⁴

Remember, repeated addition, (n+n+n) is 3n. Repeated multiplication, (n•n•n) is n³.

Hope this helps.
