Answer:
y + 163 = 41
Step-by-step explanation:
I think you are correct. It should be y + 163 = 41
The formula for area is L * W. So, this is 4*4 3/4= 19ft^2
We first have to find the first derivative before we can find the second. First derivative with respect to x is

so

and

. That's the first derivative. Now for the second it's probably easiest to use the quotient rule, even though it's usually long and drawn out. That looks like this:
![\frac{dy}{dx}= \frac{4y^2(-6x)-[-3x^2(8y \frac{dy}{dx})] }{(4y^2)^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bdy%7D%7Bdx%7D%3D%20%5Cfrac%7B4y%5E2%28-6x%29-%5B-3x%5E2%288y%20%5Cfrac%7Bdy%7D%7Bdx%7D%29%5D%20%7D%7B%284y%5E2%29%5E2%7D%20%20)
which simplifies a bit to

. We will multiply both sides by that denominator to get rid of it which leaves us with

. Get both dy/dx terms on the same side, and then factor it out.

. Divide to isolate the dy/dx:

. There's no simplifying you could do after that that would make any significant difference.
