I got the answer, thanks. It's eighteen.

Unfortunately, 9 is wrong, but thanks for trying!

That should be the anser, but it's not. Strange. Thank so much anyways! :)

$a=(bh)/2$

a=((6)(8))/2

a=48/2

a=24 u^2

After 10 students dropped from the Chinese class, we have: (C - 10) + S + (N + 10) = Total number of students.

That is not true. Just because people dropped from the Chinese class (hence the -10) doesn't mean that they weren't in the Spanish class, so you can't do N+10.

Thank you so much for trying, though. I really appriceate your effort!

b=-x-16/x

You were close, guest, but when you solve for x, x=-5.

4x+10=2x

-2x.     -2x

2x+10=0

     -10 -10

2x=-10

/2.    /2

x=-10/2

x=-

But your first steps were correct, so kudos to that!

According to google, it's 6x^2-5x+4

Thank you so much everyone!
