Option d - I and III.
Step-by-step explanation:
Given : If 
and x and y are positive integers.
To find : Which of the following must be an integer?
Solution :
As we see all option there is a multiple of y.
So, we factoring the number 375
i.e. 
In order for 375y to be a perfect square,
The prime factorization of y must contain at least one 3 and one 5.
or y must be a multiple of 15.
If y is a multiple of 15, then 
must be an integer.
and 
must be an integer.
Therefore, I and III will be correct i.e. option d.
Answer:

Step-by-step explanation:
-16x must be split into two terms that can be added to get -16, and multiplied to get 64. The only two terms that can satisfy this, is -8.
(x - 8) (x - 8)
If you're unsure about whether it's correct, you can multiply the two together to see if you get your original expression, 
, as your answer.
