Which is the first step in solving x - 4 = 4
Add 4 to the left side.
Subtract 4 from the left side.
Subtract 4 from both sides.
Add 4 to both sides.

the first question mark is 6 and the second question mark is 26 (the square root)

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

answer: i think it is (1,-2)

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
