The length of segment EF is 12 cm. Which statements regarding triangle DEF are correct? Select three options. EF is the longest side of △DEF. DF = 6 cm DE = cm DF = cm DE = cm

(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

sorry, i can't understand your question. will later if you describe more clearly!
