(x+4)(x-1) which expanded out gives
x^2+3x-4
Answer:
In order to solve this problem, we need to know the volume of a sphere.
The volume of a sphere is (4/3)pir^3
In this case our r value, or radius, is 30cm.
If we plug in 30cm to the equation like so:
(4/3)pi(30)^3
The answer is 113097 cm^3 of air

Answer:
k - 3
Step-by-step explanation:
In this expression, only 8k and 7k can be subtracted. This is because they have the same variable, meaning they are "like terms".
8k - 7k - 3 = 1k - 3
If you are simplifying, add -8m^3 and 7m^3 to get -m^3 which gives you an answer of -m^3 + 9n.
hope i helped you today!
