Answer 12

Answer 13

Answer 14

im still confused

Answer 15

Ok:) let me try and write it out.
So the denominators are 7 and (x+5) and you got the common demoninator 7(x+5)
So you have to multilly the top also. Which looks like:
((×+4)(×+5))/7(×+5) - ((7)(×+3))/7(×+5)

Answer 16

\[\frac{ x+4 }{ 7 }-\frac{ x+3 }{ x+5 }\]\[\frac{ (x+4)(x+5) }{ 7(x+5) }-\frac{ 7(x+3) }{ 7(x+5) }\]\[\frac{ (x ^{2}+9x+20)-(7x+21) }{ 7(x+5) }\]
