Answer 2

1. 3⁴+9=
First you have to do the exponent which will give you 81 then add 9 so you would get 90. (Try to practice)
2.5(d+1)
Distribute. That would give you 5d+5.
3.
3(6m)+m
Distribute 3 to 6m and that would give you 18m+m at them and you would get 19m.
4.
8x-2y+x+x
Add all x's. 10x-2y Would be the answer.
5.
17a+24b
Im not sure cause 17 is a prime number. But if 17 was 16 it would be B.
Hope this helped! Try doing there equations on your own or practicing on your own :)
