Question 1016708
.
I'm utterly confused by this question...

The length of a golden rectangle is equal to {{{x+x*sqrt(5)}}}. If x = {{{sqrt(5)}}}, what is the length of the golden rectangle?

Thanks to anyone who can help :)

<pre>
Simply substitute {{{sqrt(5)}}} instead of x. You will get

{{{sqrt(5)}}} + {{{sqrt(5)*sqrt(5)}}} = {{{sqrt(5)}}} + {{{5}}}.
