C.
You can factor that equation to the following:
x(x - 3)(x + 2)
Then set each part equal to zero and solve individually.
-13is negative and is 13 spaces away from 0. 15 is positive and is 15 spaces away from 0.
Answer:
<h2>E. 22</h2>
Step-by-step explanation:
<em>Look at the picture</em>.
The lines <em>l</em> and <em>m</em> are parallel, therefore alternate interior angles are congruent.
Therefore 
Supplementary angles add up to 180°.
Therefore
<em>add 16 to both sides</em>
<em>subtract 5x from both sides</em>

We know: the sum of the triangle angle measures is 180°.
Therefore we have the equation:

Answer:
499
Step-by-step explanation:
9,999 would be the greatest value
9500 would be the smallest value
if you subtract them you'll get 499
