For this case we have the following quadratic equation:

Dividing by 3 to both sides of the equation we have:

We take common factor "x" from the left side of the equation:

Thus, the values of "x" that satisfy equality are:

Answer:
The solutions are:

Answer:
b c
Step-by-step explanation:
we can divide this shape into two parts
(1) Hemisphere:
we can see that
radius is 8
now, we can use formula for volume



(2) Cylinder:
radius is 8
height is 7
we can use formula



now, we can add them to find total volume
