Answer:
The correct option is c.
Step-by-step explanation:
The quotient of the polynomials is

We need to find the remainder by using long division method.
The dividend of the given expression is


The long division method is shown below.

From the below attachment it is clear that the quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend.
Therefore the correct option is c.
Answer: 2√5 - 3
Step-by-step explanation:

Recall your d = rt, distance = rate * time
so, keeping in mind that both trains are going at the same speed, say speed of "r" mph, after 212 hours A arrived at station A and after 4 hours, B arrived at station B.
now, the distance covered by train A is say "d", we know both stations are 585 miles apart, so, if train A covered "d" miles in those 212 hours, then train B covered the slack from 585 and d, that is "585 - d".
