@passive13, buddy we've gone over this...you cant give out an answer like that.

Answer 12

Multiply,
\[\frac{ \color{red}{(r+1)} }{ \color{red}{(r+1)} }*\frac{ (r+2) }{ (r+4) }-\frac{ \color{blue}{(r+4)} }{ \color{blue}{(r+4)} }*\frac{ 3 }{ (r+1) }\]

Answer 13

i shall start charging people then lol

Answer 14

\[\frac{ (r+1)(r+2) }{ (r+1)(r+4) }-\frac{ 3(r+4) }{ (r+4)(r+1) }\]\[\frac{ r^2+2r+r+2 }{ (r+1)(r+4) }- \frac{ 3r+12 }{ (r+1)(r+4) }\] combine.\[\frac{ r^2+3r+2-3r-12 }{ (r+1)(r+4) }\]

Answer 15

Simplify and you've got your answer.
