The figures shown are similar. what is the scale factor? a. 1/9 b. 3/7 c. 4/7 d. 6/7

C. 4/7

Step-by-step explanation:

The scale factor is the ratio of corresponding side lengths (the only ones marked with a length).

... 12/21 = 4·3/(7·3) = 4/7

(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. -82562234434584
