B B B
B is the correct answer
Answer:

Step-by-step explanation:
Recall that the equation of hyperbola centered at the origin with transverse horizontal axis has the general form:

since we know that a = 5 ,and c = 15,we can solve for b:

then the equation of the hyperbola becomes:

The LCM is the smallest common multiple. To find this, list the multiples of each number
52: 52, 104, 156....
13: 13, 26, 39, 52.....
the smallest number that is a mutiple of both is 52.
so, the LCM of 13 and 52 is 52.
Hope this helps!
