geometry question involving triangles
Hey everyone !

So my GRE exam is fast approaching (Worried)

I am trying to solve the following:

Triangles PQR and XYZ are similar. If PQ = 6, PR = 4, and XY = 9, what is the length of side XZ?

I would appreciate any explanation in the *simplest* terms possible !

Thanks much :)

From the given
$\frac{PQ}{PR}=\frac{XY}{XZ}$
