Answer:
and 
Step-by-step explanation:
Given:
The rational equation to solve is given as:

We use the cross multiplication rule and multiply the numerators one side with the denominators of the other side. Therefore,

Now, for
, the rational equation is equal to 0. So,
is a solution.
Also,
is also a solution as the equation's denominator is defined at that point.
So, no extraneous solution.
Answer:
D. 6 < x < 22
Step-by-step explanation:
<em>For a triangle, the third side must be less than the sum of the other two sides and it must greater than the difference between the other two sides.</em>
Simplify 2r + 10 + 4r to 6r + 10
Expand it
Simplify 6r + 18 - 4 to 6r + 14
Cancel 6r on both sides
Since 14 = 10 is false, there is NO solution for this equation so no answer.
The best estimate of distance between the point and the origin is 15 units. this is your answer.
15/16 is your answer.
How?
Convert mix numbers into improper fractions.
5/2 • 3/8
Now, just multiply the fractions.
