What is the x intercept of the equation 4x-3y=24

x-intercept is for y = 0.

Put y = 0 to the equation of a linear function:

4x - 3(0) = 24

4x - 0 = 24

4x = 24     divide both sides by 4

x = 6

power property.

(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
