Answer:
i pretty sure one of em is 6.12
:) Well, I dunno about anyone else but this question makes my head spin!
formula= LCM ×GCD of the numbers ÷ The first number
What factors to they have in common?
First, they're all even, so 2
if we divide all of them by 2, we get:
13,24,31
now, 13,31 are primes: so that means that those numbers don't have any more common factors!
So the greatest Common Factor of those 3 numbers is 2.
X^2 + X - 12 = 0
(X + 4)(X - 3) = 0
X = -4 and X = 3.
