Extract the normal vectors from the given planes:
(which are unique up to their signs, meaning either 
or 
are valid choices for the normal vector)
The third plane must be perpendicular to both these given planes, which means it would be parallel to both and 
, which in turn means its own normal vector 
should be perpendicular to both and .
Enter the cross product:
or (4, 5, 3), which also works.
The given plane passes through (-1, 1, 4), so its equation is
Simplify:
Answer:
0 and 8.
Step-by-step explanation:
n^2+8n=0
n(-n+8)=0
-n=-8 or n=8 and n=0.
Answer D The binomial must start at 0, but can increase to an infinite upper limit. Hope that helps.
Rx+h=sx-k
Rx-sx=-k-h
x(R-s)=-k-h
x=(-k-h)/(R-s)
Answer: <span>x=(-k-h)/(R-s)</span>
The answer would be three because four is too much
