Step-by-step explanation:
In the 
plane, we have 
everywhere. So in the equation of the sphere, we have
which is a circle centered at (2, -10, 0) of radius 4.
In the 
plane, we have 
, which gives
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the 
plane, 
, so
which is a circle centered at (0, -10, 3) of radius 
.
Answer:
28 -16n
Step-by-step explanation:
Use the distributive property, then collect terms.
4 +8(-2n +3)
= 4 +8(-2n) +8(3)
= 4 -16n +24
= 28 -16n
_____
This could also be written
-16n +28
but then the leading sign would be negative. Sometimes leading minus signs get lost, so I prefer the first term to be positive.
