A triangle is rotated 90° about the origin. Which rule describes the transformation?
VA
(x, y) - (x,-)
(x, y) - 6-y, x)
(x, y) - (-, -x)
(x, y) - (y. -x)

(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

the answer is 13 cm
