Is the figure, z || y and a is a transversal that crosses the parallel lines.

which angle pair forms alternate interior angles?

a. < 4 and < 6
b. < 1 and < 8
c. < 3 and < 7
d. < 2 and < 6

d

Step-by-step explanation:

(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
