The equation is 50+10x-10 which would simply to 40+10x and then change the x to 5 ( now it’s 5 times 10 ) changing 10x to 50 . 50+40 equals 90 . GOOD LUCK
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;
That does look impossible someone plz help this man out or girl I don’t wanna assume genders ya know
