Answer:
the answer is A
Step-by-step explanation:
Answer:
B. 
Step-by-step explanation:
We have been given a rational expression 
and we are asked to simplify our rational expression.
We can see that our denominators are not equal. Since the two denominators do not share any common factors, the common denominator is simply the product of these two denominators.
To keep the value of expression same we will multiply the same quantity with numerators and denominators.
Now let us simplify our expression using FOIL.
Now we have same denominators, so we can add our numerators.
Now let us combine like terms.
Therefore, the simplest form of our given rational expression will be and option B is the correct choice.

<span>2. A pool company is trying out several new drains. Drain A empties a pool at a rate of 2 gal/min. Drain B empties a pool at a rate of 5 gal/min. One pool has 108 gal of water in it. Write an equation for each drain that shows the amount of time it takes to empty the pool. Then solve each equation showing your work.</span>
Drain A: rate is 2 gal/min. We do not know which pool has 108 gallons of water in it. If it's Pool A, then the time required to empty Pool A is
108 gallons
------------------- = 54 minutes
2 gallons/min
If it's Pool B, then we can represent the amount of water in Pool B by b. Then the time required to empty Pool B is
b (gallons)
------------------ = (b/5) minutes
5 gallons/min
