Your 3rd option, or (-6,-3,0,3,6) would be the answer
Answer:
5ft
Step-by-step explanation:
all sides of a square are equal and there are 4 sides so divide 20 by 4 and you get 5 ft
Answer:
(-1,1,3)
Step-by-step explanation:
midpoint = (x1+x2/2, y1+y2/2, z1+z2/2)
midpoint = ( (-6+4)/2, (3+-1)/2, (4+2)/2 )
midpoint = (-2/2, 2/2, 6/2)
midpoint = (-1, 1, 3)
Answer: this is our required factor i.e.

Explanation:
Since we have given that

As we know the identity , which says that

So, we can use this here ,

Hence this is our required factor i.e.

X=-4 cause
-2=x+2
Then -4=x
