Question

Solve for x.

6 over x equals x over 12

Answer 1

6/x = x/12

\[\frac{ 6 }{ x } = \frac{ x }{ 12 }\]

so cross multiply to get x^2 = ...something
then solve for x

Answer 2

multiply both sides by 12.

Answer 3

yep,
and then multiply both sides by x

Answer 4

that way u get rid of the 2 denominators (12 and x)

Answer 5

which simplifies to 72

Answer 6

on the LHS, yep
so what does the RHS equal...?

Answer 7

x

Answer 8

nope, x^2

\[x ^{2}\]

Answer 9

so then square 72

Answer 10

times both sides by 12
6/x * 12 = x/12 * 12
72 / x = x

then both sides by x
72 / x * x = x * x
72 = x^2

so x = sqrt 72

\[x = \sqrt{72}\]

Answer 11

yep, and sqrt 72 =...?

Answer 12

\[6\sqrt{2}\]

Answer 13

cool, i woulda gone with 8.5 ish, but yours is way more exact ;)
understand it all tho dude?
