Final answer:

The equation that shows the difference between the number of factors in 18 and the total number of factors in a prime number is 6 - 2 = 4. The correct answer is C.

Step-by-step explanation:

The question asks for the equation that shows the difference between the number of factors in 18 and the total number of factors in a prime number. We can start by finding the factors of 18, which are 1, 2, 3, 6, 9, and 18. The total number of factors in 18 is 6. Since 18 is not a prime number, we need to find the total number of factors in a prime number.

A prime number is a number that is only divisible by 1 and itself, so it has exactly 2 factors. Therefore, the total number of factors in a prime number is 2.

To find the difference between the number of factors in 18 and the total number of factors in a prime number, we use the formula: number of factors in 18 - total number of factors in a prime number.

The correct equation is 6 - 2 = 4.

Answer:To find the difference between the number of factors in 18 and the total number of factors in a prime number, we need to determine the number of factors in each number and subtract them.

Let's start with 18. The factors of 18 are 1, 2, 3, 6, 9, and 18, so there are 6 factors.

Now, let's consider a prime number. A prime number only has two factors, 1 and itself. Since 2 is the smallest prime number, it has 2 factors.

To find the difference, we subtract the number of factors in a prime number from the number of factors in 18.

6 - 2 = 4

Therefore, the correct equation that shows the difference between the number of factors in 18 and the total number of factors in a prime number is:

B. 6 - 2 = 4
