Hello :
the normal vector of the plane is : d' = [4,-1,5]...(vector perpendicular to the plane)<span>
d </span><span>⊥ d' because : (4)(2)+(-1)(3)+(5)(1)=0
</span>the line is perpendicular to the plane .
X+(x+2)+(x+4)= 66
3x+6=66
3x=60
x=20
20,22, and 24. so 20 is the answer
They have a scale factor of 5:6 so first we need to find the perimeter of KLM:

Then apply the scale factor of 5:6:

Set the denominators equal:

So we see that the perimeter of GHJ is 35.
Answer: its 50
