36 = 6×6 or 4×9 or 2×18 or 1×36
6×6 does not work because 6 + 6 + 6 + 6 = 24
4×9 does not work because 4 + 4 + 9 + 9= 26
2×18 works because 2 + 2 + 18 + 18 = 40
No need to check other option
Therefore sides of rectangle is 2" and 18"
Step-by-step explanation:
The equation of a parabola that relates it focus is

So here, we isolate x^2.


Next, we factor out 4.

Our p=8 so this tells us the distance of the vertex to the focus.
First
we have to understand what the domain is. In a nutshell the domain is
the set of all x values that are represented in any given graph. In
this case we do not have a graph but we have the vertex. The x value
is 2, therefore: x
≥ 2.

hope this helps, Regards.
