anonymous · Answer

how do i go from there?

anonymous · Answer

you can cancel out the (x-5)

anonymous · Answer

thats what i thought , what would i do from there though?

anonymous · Answer

then you would have 4x+3/x+3
not much you can do.
what was the question asking you do?

anonymous · Answer

This is what the question says, Use your understanding of multiplying and dividing fractions to rewrite the expressions below. Then look for "ones" and simplify. For each rational expression, also stadte any valuses of the varibles that would make the denomintaior zero. here is the full question... http://hotmath.com/help/bookindexes/cpm06/index.html?myhm=true#pid=cpm06_10_1_Classwork_10-15_412

anonymous · Answer

valuses of the varibles that would make the denomintaior zero
would be x= -3

anonymous · Answer

valuse of the variable that would make the denomintaior zero would be x= -3

anonymous · Answer

how did you come to find that?

anonymous · Answer

valuse of the variable that would make the denomintaior zero would be x= -3

anonymous · Answer

what is the simplified version?

anonymous · Answer

this is the simplest 4x+3/x+3
nothing else you can do

anonymous · Answer

$$x \neq -3$$
then the whole thing would be Undefined Slope, No Slope
