Answer:
10 
Step-by-step
Reduce 
to 
and simply subtract.
Volume of Sphere = (4/3)*(pi)*(r^3)
r = (D/2) = 6 m
=<span>(4/3)*(pi)*((6^3)
= 904.7786.. m^3
I hope this helps.</span>

Answer:
- (x +1)² = 4
- (D) x = -1 ±2
Step-by-step explanation:
Start by getting the x-terms on one side of the equal sign. We can do that by subtracting x from both sides.
3 = x² +2x
Now, add the square of half the x-coefficient.
3 +1 = x² +2x +1
(x +1)² = 4 . . . . . . . . write as a square in the desired form
__
To solve, take the square root, and add the opposite of the left-side constant.
x +1 = ±2
x = -1 ±2 . . . . . . matches choice (D)
In general polynomial <span>is an </span>expression<span> consisting of </span>variables<span> (or </span>indeterminates<span>) and </span>coefficients<span>, that involves only the operations of </span>addition<span>, </span>subtraction<span>, </span>multiplication<span>, and non-negative </span>integer exponents<span>.
So this equation is polynomial</span>
