Answer:
I think it's 12 a⁹ b⁷ correct me if I'm wrong
Which is the side length of a cube with a volume of 64 m3?
<em>Volume: 64m</em>³
a^3 = 64
<span>\sqrt[3]{64}</span> [/tex] = 4 m
↑
the answer
Check
4 * 4 * 4 = 64 m³
Given:
<span>x^2 + y^2 + z^2 + 2x − 2y − 2z = 22
group the variables
x^2+2x + y^2-2y +z^2-2z = 22
then complete the squares
x^2+2x+1 </span>+ y^2-2y+1 + z^2-2z+1 = 22 +1 +1 +1
factor and simplify
(x+1)^2 + (y-1)^2 + (z-1)^2 = 5^2
Interpretation:
The centre of the sphere is at (-1,1,1) with a radius of 5
