solve by cross multiplication x=14*4/16=56/16=3.5

N is inversely proportional to A so N*A=constant N*A=3*15=45 if A becomes 5,N will be 45/5=9

hello emily,remember the properties of modulus |4x + 3| = 9 + 2x case1 4x+3=9+2x =>x=3 case2 -4x-3=9+2x =>x= -2

15*3=5*A so A=5

one student's position is fixed .now the remaining 8 students can give their presentations in 8! ways 8!=8*7*6*5*4*3*2*1=40320

-3 -5 -2 -4 -1 -3 0 -2 1 -1 this is the table All numbers in input and output are in ascending order

n. 9n=3(nP2) =>9n^2=3(n!/(n-2)!) =>9n^2=3(n*(n-1)(n-2)!/(n-2)!) =>9n^2=3(n*(n-1)) =>9n^2=3(n^2-n) =>9n^2=3n^2-3n =>6n^2-3n=0 =>3n(n-2)=0 =>n=0 and n=2

Did you understand harley?

very simple lily x> -15 => x+15>0

oops,I made a mistake 6n^2+3n=0 => 3n(2n+1)=0 =>n= 0 and n= -1/2
