Best ResponseYou've already chosen the best response.1(2(3)+6) / (4(3)8) = 0/20 (2(2)+6) / (4(2)8) =2/16 (2(0)+6) / (4(0)8) =0/0 (2(2)+6) / (4(2)8) =10/0

Best ResponseYou've already chosen the best response.1that didn't really get us anywhere let's just use algebra \[\frac{ (2x+6) }{(4x8) } = \frac{ 2(x+3) }{ 4(x2) }\]

Best ResponseYou've already chosen the best response.1we want to find the value where the expression is undefined which happens when the denominator is zero. so what we have to do is make the denominator zero so what would make \[4(x2) =0?\] when x=2 because \[4(22)=4(0)=0\] so D is your answer
