Question

Which of the following statements best describes the value of the expression 18x – 35, when x = 2?
A. The result is not a whole number.
B. The result is a prime number.
C. The result is a composite number.
D. The result is a whole number that is neither prime nor composite.

Answer 1

Answer:

D

Step-by-step explanation:

Let's plug 2 in for x:

18 * 2 - 35 = 36 - 35 = 1

Now, look at the answer choices:

A) Well, 1 is a whole number; it's not a fraction or a decimal. So eliminate A.

B) 1 is not a prime number; the smallest prime number is 2. So eliminate B.

C) 1 is also not a composite number; the smallest composite number is 4. So eliminate C.

D) This is true. 1 is a whole number, but it's not prime or composite, as seen above.

Thus, D is the answer.
