Using number sets, it is found that the correct classification of the number is:
C. rational number, integer, whole number, natural number , real number.
Numbers are classified as:
- Whole, which is all positive numbers and zero, also called natural.
- Integers, which is the set of whole numbers plus negatives.
- Rational, which is the set of integer numbers plus terminating or repeating decimals.
- Irrational, which are non terminating decimals.
- Real, which are the sum of rational and irrational.
In this problem, the number given is:

- Which is a whole(natural) number, thus it is also integer, rational and real, and the correct option is C.

Answer:
0
Step-by-step explanation:
81 square inches
9*9*9=729
729/9(height of cube)=81(length and width of cube=area of cube)
We have that
the slope of the line that is parallel to x=-3 is classified as undefined.
<span>let's check the answer
</span><span>1) take any two points of the line x = -3
</span>point A (-3,0) point B (-3,5)
2) find the slope of the line x=-3
m=(5-0)/(-3+3)=5/0----------> is undefined
the answer is the option undefined
