What is the solution(s)?

x = 2

Step-by-step explanation:

-12 = -3x²

divide through by -3

-12/-3 = -3x²/-3

4 = x²

square root both sides

[4]^½ = x²× x^½

so therefore: 2 = 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

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35
