The answer is B. Dbsjskkdjcjdks
So, let's solve all of them and see:
a - (-b) = a + b ⇒ can be either positive or negative, depending on the numbers
a + (-b) = a - b ⇒ can either be positive or negative, depending on the numbers
a * (-b) = a * (-b) ⇒ negative answer no matter what
a / (-b) = a / (-b) ⇒ negative answer no matter what
So the answer is:
<em>"None of the above"</em>.

The volume of a sphere is defined as:
V=(4*pi*r^3)/3
then, if we double the radius of the sphere (r=2r):
V=(4*pi*(2r)^3)/3
V=(4*pi*(2^3*r^3))/3
V=(4*pi*r^3)/3*8
Then, the answer is that if you double the radius of the sphere, its volume is increased 8 times.
Answer:
3x + 5 = 45° + x
In here we can fine like terms by putting the unknown terms together and the whole numbers together example:
3x - x = 45 - 5
After that you can get the value of x
So,
2x = 40
x = 20
