<span>A sphere is a perfectly round geometrical object that is three dimensional, with every point on its surface equidistant from its center. Many commonly-used objects such as balls or globes are spheres. If you want to calculate the volume of a sphere, you just have to find its radius and plug it into a simple formula, V = ⁴⁄₃πr³</span>
Foil the right side. Multiply first, outer, inter, and the last terms. The right side is equal to x^2 + 11x + 18x. N is 11.
First of all, let's find the slope of line L. To find the slope of a line, you write it in the explitic form
, and consider the coefficient
. So, we have

So, the slope of line L is 2/3.
Two lines are parallel if they have the same slope. So, line M has slope 2/3 as well, and we know that it passes through the point (3, -10).
When you are given the slope
and a point
of a line, its equation is given by

So, if you plug your values, you have

which you can simplify into
