Question

I really need help on this!

Answer 1

Explanation:

`(2)/(x) = (x)/(18) \\\\ x^2 = 36 \\\ x = \pm 6`

I hope I helped you.

Answer 2

`(2)/(x)=(x)/(18)` Cross multiply (multiply 18 on both sides to get rid of the 18 in the denominator, and multiply "x" on both sides to get rid of the x in the denominator

`(18)(2)/(x)= (x)/(18)(18)`

`(36)/(x)=x`

`(x)(36)/(x)=x(x)`

36 = x² Square root both sides to get rid of the ², and to get "x" by itself

√36 = √x²

±6 = x Your answer is 6

You could have just done this too:

`(2)/(x)=(x)/(18)`

2(18) = x(x)

36 = x²

√36 = √x²

±6 = x
