Best ResponseYou've already chosen the best response.3\[\frac{5a^25.1^2}{a1}=60\] \[5a^25=60(a1)\] \[5a^25=60a60\] \[5a^260a5+60=0\] \[5(a^2120a+11)=0\]

Best ResponseYou've already chosen the best response.1\[\frac{5a^25(1)^2}{a1}=60=> \frac{5(a^21)}{a1}=60\] \[=>\frac{5(a1)(a+1)}{a1}=60 => 5(a+1)=60=> a+1=12\]
