Please help with linear models

the bottom right

Step-by-step explanation:

all of the dots are around one area that seem to form a line

(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 equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
