Step-by-step explanation:
a. that's the best answer that suits the question per day you multiply by 22
The greatest common factor would be xy^2 because these are the only factors that they all have in common. The second term only has 1 x, so only 1 x is part of the gcf.
The 1st and 3rd terms each have y^2 therefore making it part of the gcf as well.
The anwser is C!!!!!!!!!!!!!!!!!!!!!! ik this because i calculated it my self
X - the volume of the tank

The tank holds
375 liters when full.
Answer: The correct option is (c) 
Step-by-step explanation: We are given to solve the following quadratic equation by the method of completing the square:

Also, we are to find the constant added on both sides to form the perfect square trinomial.
We have from equation (i) that

So,

Thus, the required solution is
and the value of the constant added is 
Option (c) is correct.
