Answer:
i think it is 180
Step-by-step explanation:
because 180 is the total degrees of a triangle
We haven n! = (n-1)! x n and (n+1)! = n! x (n + 1);
Then, (n!)^2 = n! x n! = n! x (n-1)! x n;
And (n+1)!(n-1)! = n! x (n + 1) x (n-1)!;
Finally, [n! x (n-1)! x n] / [n! x (n + 1) x (n-1)!] = (n+1)/n;
Answer:
x ≤ 1
Step-by-step explanation:
8 + 4x
12
4x
12 - 8
4x ≥ 4
Dividing both sides by 4 gives;
x ≤ 1
