28a⁴b: 2 · 2 · 7 · a · a · a · a · b
16ab: 2 · 2 · 2 · 2 · a · b
GCF(28a⁴b, 16ab) = 4ab
The answer is A.
Answer:
the question is incomplete, the complete question is
"Finding Derivatives Implicity In Exercise,Find dy/dx implicity . 
"
Answer : 
Step-by-step explanation:
From the expression " y is define as an implicit function of x, hence we differentiate each term of the equation with respect to x.
we arrive at
for the expression 
we differentiate using the product rule, also since y^2 is a function of y which itself is a function of x, we have
.
if we make dy/dx subject of formula we arrive at
By pythagorean theorem
a^2+b^2=c^2
We can find that PL is 12.65
and then by altitude theorem
MA*LA=PA^2
we can find the value of MA
12MA=16
MA=1.33
then by the pythagorean theorem
we can use to find PM
MA^2+PA^2=PM^2
so PM=4.22
then to find the are you multiply length by width
PM*PL
12.65*4.22
So the area is 53.38
Ok so in order to do that you need a calculator
