To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above:
<span>7/x^2-3x - 1/x^2-9
</span>
2. When you factor the denominator, you obtain:
<span>7/x(x-3) - 1/(x+3)(x-3)
3. By simplifying the expression, you obtain:
3(2x+7)/x(x+3)(x-3)
</span> 3(2x+7)/x(x^2-9)
The answer is: 3(2x+7)/x(x^2-9)

Step-by-step explanation:

hope it's helpful dear :)
State A has 25 drive-in movie screens and State B has 21. You find this by guess-and-checking different numbers that you could add together to get 46. You want to do numbers that are relatively close, as a difference in 4 is not much at all. You can divide 46 by 2 and then play around from there.
Answer:
B
Step-by-step explanation:
Using the Sine Rule in ΔABC
=
= 
∠C = 180° - (82 + 58)° = 180° - 140° = 40°
Completing values in the above formula gives
=
= 
We require a pair of ratios which contain b and 3 known quantities, that is
= 
OR
=
→ B
