Answer:
28 meters cubed.
Step-by-step explanation:
Since we know that the volume of a sphere is 4/3 the volume of a cylinder, we can multiply 21*4/3. 21*4 will equal 84 and 84/3 would be 28. So the volume of the sphere would be 28 meters cubed.

105/5=21
Answer:
x = 6
Step-by-step explanation:
44 + 3x = 5x + 2x + 20 transfer like terms to the same side of the equation with the opposite sign:
44 - 20 = 5x + 2x - 3x add/subtract like terms
24 = 4x divide both side by 4
6 = x
Answer:
We have to evaluate the function p with the numbers on the argument of them, that is:
p(-5) = -11887
p(3)= -191
Step-by-step explanation:
First we are going to evaluate the functions and then to replace x by the corresponding number on the argument:
p(-5)= 2 (-5)^5 -9(-5)^4 -2(-5)^2+12(-5) +2 = -11887
p(3) =2(3)^5-9(3)^5-2(3)^2+12(3)-2 =-191
