Question

solve for x ? 8/x=x/11

Answer 1

cross multiply to get
\[x^2 = 88\]can you solve for x now?

Answer 2

no

Answer 3

square both sides to just get x
You should get \[x = \pm \sqrt{a}\]

Answer 4

a represents 88, obviously.

Answer 5

\[\frac{ 8 }{ x } = \frac{ x }{ 11 }\] cross multiply
x^2 = 88
square root both sides
\[x = \pm \sqrt{88} = \pm 2\sqrt{22} \approx 9.3808\]
