Hello,
if 2x²=54 then (2x)²=4x²=2*2x=2*54=108
Write and solve an equation of ratios:
900 students 45 teachers
------------------ = -----------------
x 110 teachers
Cross multiplying, we get (900)(110) / 45, or
so x = # of students in the high school = 2200 (answer)
Answer:
<h2>A.6% Is the correct answer... </h2>

For twice a number we can use the variable x
For four times a number we can use the variable c
4c - 2x + 15
I believe this is correct although I'm not 100% sure
