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) = 3Area scale factor (a.s.f.) = 32 = 9New area = original area x (a.s.f.) = 20 x 9 = 180 cm2
first: look at the 2 equations and see if there are any matching coefficients. eg the same number before x or y in both of the equations. in these examples both y values have the coefficient 1. second: ei...

First of all, if not already done, you would arrange all the x's or whichever letter used on one side of the inequality. E.g. for x2+ 19x - 5 < 6x - 45 you would arrange it like: x2ACAnswered by Asha C. • Maths tutor2484 Views
