Answer:
-2x-5y+8z+4.5=0
Step-by-step explanation:
Let (x,y,z) be the coordinates of the point lying on the needed plane. This point is equidistant from the points (-3, 5, -4) and (-5, 0, 4), so

The radius is half of the diameter.
To find the circumference, use the equation C=2(pi)r or C=(pi)d.
r meaning radius. d meaning diameter.
(pi) is about 3.14 or 22/7

Answer:
D) -9 + 9
Step-by-step explanation:
The Additive Inverse Property is where the sum of any number and its inverse (opposite) is zero. In this case, we need to have an expression that equals zero, and two numbers that are opposite of each other. This would be D) -9 + 9 because these two numbers are inverses of each other, and the expression equals 0.
