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.

Answer:
1) 
.
2) 
years
Step-by-step explanation:
Let Hanna's sister be 
years old.
Then Hanna will be 
years old.
The sum of their ages will be 
years.
The statement "no more than 18" means the sum of their ages is less than or equal to 18.
The required inequality is;
.
2)
The inequality we just found is
.
We simplify to get;
.
we divide both sides by 
to get;
.
Therefore the oldest age Hannah's sister can be is years
