Imagine you want to sail a ship from Liverpool to new York. While sailing you will need to know precisely what direction you need to be travelling at every point(if you are out by one degree this could re...

First we solve 6-3n>18. We do this by rearranging:Carry over the -3n term for 6>18+3n.Take away 18 from both sides for -12>3n.Divide both sides by 3 for -4>n.So we know that n<-4. Now we so...

Length scale factor (l.s.f) = 3
Area scale factor (a.s.f.) = 3² = 9
New area = original area x (a.s.f.) = 20 x 9 = 180 cm²
