Step-by-step explanation:

QUESTION 2

An integer is a whole number, and a "real number" is any number that is rational or irrational or an integer.

With respect to this  question,

A. Is not an integer. The square root of 7 is an irrational number, which basically means that its a long  decimal and can't be written as a fraction. Perfect squares are numbers in which the square roots are whole numbers, with no decimals.

B. Is not an integer. 0.15 sis not  a whole number, and in order to be an integer, it must be a whole number.

C. Is an integer. It is a whole  number. Note that negative numbers can be integers, as long as they are still whole numbers.

D. is not an integer; its a fraction.

So the answer is  C.
