<h2>442 people named neither blue nor red.</h2>Step-by-step explanation:
Givens:
people named blue.
people named red.
- The total number of people is 1092
So, we first have to calculate the number of people that named blue and red.
This means that 468+182=650 people named blue or red.
If we find the difference between 650 and 1092, we would have the total number of people that didn't named blue nor red.
1092-650=442.
Therefore, 442 people named neither blue nor red.

Answer:
Step-by-step explanation:
Let:
This is an exact differential equation because:
With this in mind let's define f(x,y) such that:
and
So, the solution will be given by f(x,y)=C1, C1=arbitrary constant
Now, integrate with respect to x in order to find f(x,y)
where g(y) is an arbitrary function of y
Let's differentiate f(x,y) with respect to y in order to find g(y):
Now, let's replace the previous result into :
Solving for
Integrating both sides with respect to y:
Replacing this result into f(x,y)
Finally the solution is f(x,y)=C1 :
