Answer:
Step-by-step explanation:
When y varies jointly as x and z, the equation is written ...
y = k·x·z
Here, the joint variation is not with z, but with z². There is also an inverse variation with w, so the entire relation is ...
y = k·x·z²/w
We want to find the value of k for the given values of the variables. So, we can solve for k to get ...
Then the equation of variation is ...

Let us call the distance AB of Y (in the problem nothing is said about this dimension, so lets call of Y).
From the attached drawing we can conclude that:
AB + BC = AC
where
AB = Y
BC = 2X + 4
AC = 24
then
AB + BC = AC
Y + (2X + 4) = 24
<h2>X = (20 - Y)/2</h2><em>In my view this question is incomplete</em>
