Point J is on line segment IK. Given JK = 2x, IJ = 5x, and IK = x + 6, determine the numerical length of JK.

Step-by-step explanation:

Given:

Required

Solve for JK.

Since J is on IK, we have:

Collect Like Terms

Solve for x

Substitute 1 for x in

(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

definitely a. the others have almost all data points on one side of the line.
