Answer:
You cannot solve by factoring
Step-by-step explanation:
We want to solve 
by factoring.
We can rewrite as: 
So we have a quadratic equation in 
.
We split the middle term to get:
We look for factors -28 that sum up to -6
This is not possible hence the given equation is not factorable
4 on the outside with three in the inside
Answer:
Below in bold.
Step-by-step explanation:
If the 3 points are on the circle with the given center then the distance from each point to the center will all be equal. This distance will be the radius of the circle.
Distance of P (2, 5) from the center (4, 2)
= √( (5-2)^2 + (2-4)^2)
= √(9 + 4)
= √13.
For Q (6, -1)this distance is:
= √(6-4)^2 + (-1-2)^2)
= √13.
For R (7, 4) his distance is:
= √(7-4)^2 + (4-2)^2)
= √13
These distances are the same so the points P, Q and R lie on the circle.
The midpoint of PQ
= (2+6)/2 , (5 - 1)/2
= (4, 2).
Which is the center so this verifies the second part.
I believe the answer is 4030mL because 4880-850= 4030mL
