Write as an algebraic expression

13) x=n-11

15) x=3*10

Step-by-step explanation:

I used x as the variable. The questions are pretty straightforward. They are asking you to put the terms in the description on the right side of the equation. The questions = x. That was probably confusing, but it is correct. I hope this helped!

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
