Hey!
I believe the correct answer is: C. Poetry.
By making the determinant equal to or smaller than zero, we will see that there are 15 values of n such that the inequality has no real solution.

Solving the inequality:</h3>
Here we have the inequality:
x^2 + n*x + 15 < 0
We want to see for which values of n we don't have real solutions.
Now, we can write the quadratic equation:
y = x^2 + nx + 15.
If the determinant of this quadratic equation is negative or 0, then we have a single root or we don't have roots, and because the leading coefficient is positive, that would mean that the function never becomes negative. Then for these cases, the inequality has no real solutions.
Then we must have:
n^2 - 4*15*1 ≤ 0
Now we can solve this for n.
n^2 ≤ 60
Then if n^2 is smaller than 60, we don't have real solutions, and we know that:
√60 = 7.75
Then we have:
-7.75 ≤ n ≤ 7.75
But n can only be an integer, so we can write:
-7 ≤ n ≤ 7
From -7 to 7 there are 15 integers, then there are 15 values of n such that the inequality has no real solutions.

Answer:
The poultry house must have to be well ventilated.
Ensure sufficient entrance of sunlight and fresh air inside the house.
It would be better if the house become situated north to south faced.
The proper distance of one house to another house is about 40 feet.
Clean the house properly before keeping the birds inside the poultry house.
Make a deep liter and keep it dry and clean always.
Wooden and rice bran can be used for making liter.
Keep feed and feeding equipment in proper distance inside the poultry house according to the number and demand of poultry birds.
The poultry house and all equipment must have to be free from virus, parasites and germs.
Build the poultry house in such a place where all the poultry birds are free from all types of wild animals and other predators.
The poultry housing area will be free from loud sound/sound pollution.
Make the poultry house in quite and calm place.
It would be better if the house located in an open air place.
However, to be successful in poultry farming the producers must have to be aware in making the poultry house. Be sure that all necessary equipment and facilities are available inside the poultry house.

Explanation:
All but kg can be vector quantities.
m/s^2 is acceleration. in the formula F = m*a the acceleration has direction and that means that force has direction. If you place an object on a table, there are 2 vectors in operation: one tends to move down (gravity) and one points up (the table top). The object would like to move but cannot, because the forces are equal but in opposite directions.
meters can be a vector or the unit of a vector. It is called displacement when it has direction.
km / hr. Since meters can be a vector, so can km. This is a velocity (or can be). When the direction is not specified, km/hr is a speed. It might describe the movement of a snail. hours really have no direction. hours can't go up, or down or left or right, the way km can. So hours add nothing to the question.
kg are units of mass. Mass really has no direction associated with it. Don't confuse mass and weight. Weight does have a direction, but mass does not.
True. A nuclear family includes a couple and their dependent children. Now a days there are many types of families like single parent families, extended families, childless families, step families, etc.
