Answer:
Step-by-step explanation:
Given is an equation in x and y as

We use implicit method to differentiate the above equation
18x-2yy'=0
y' = 9x/y
b) to solve the equation explicitly for y and differentiate to get y' in terms of x. y' = ±
We separate the variables as

Take square root

I want to say either rectangular prisim or triangle pyrimad
7623, 27.8, 76.9, and 8401 it is really simple just use a calculator........
