# Inequalities Watch

Announcements
1. The question is 2(13+2x)<(6+x)(1-x) and I already got the solutions which are x>-5 and x<-4
But using the graph I'm not sure if it would be -5<X<-4 or if it would be X>-5 or x<-4. Thank you

Just get everything on one side, factorise fully, sketch the parabola and see which part of it satisfies the inequality. Show your graph if you're unsure.
