Which point is in the solution set of this system of inequalities?
y < 2x
ly j2x +4
o
a. (4,1)
o
b. none of these
o c. (0,0)
o d. (1, -2)

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

40 x 50 = 2000
