14= A.39°
You solved this one so I'm not going to show the work for it.

15=B,C,D
a.-30(-3x+2)=90x-60- incorrect
b.30(-3x+2)=-90x+60
c.10(-9x+6)=-90x+60
d.-10(-9x-6)=90x+60
e.-10(9x+6)=-90x-60- incorrect

16=D
-18x-12-(-13x+17)
-18x-12+13x+17
-5x+5

17=C
9x+3-5x-7
4x-4

18=C
You solved this one...

19=B
8.4x+2.9+(-3.7x+5)
8.4x+2.9-3.7x+5
4.7x+7.9

20=C

21=D
D is the only one that ends with +32 and not -32, which would be incorrect.

22=Cant see >.<

23=A
4x+12+15-3x
x+27

24=B
2x+3

a^{-{ n}} \implies \cfrac{1}{a^{ n}}
\qquad \qquad
\cfrac{1}{a^{ n}}\implies a^{-{ n}}
\qquad \qquad 
a^{{{ n}}}\implies \cfrac{1}{a^{-{{ n}}}}\\\\
