Final answer:
The multiplication of 9 • 4 equals 36, which is the result of adding 9 to itself 4 times.
Step-by-step explanation:
The question 'which of the following is equal to 9 • 4?' is asking us to perform a multiplication operation. In Mathematics, when we multiply two numbers, we are essentially adding one of the numbers to itself the number of times indicated by the other number. Therefore, 9 multiplied by 4, which is written as 9 • 4, is equal to adding 9 to itself 4 times: 9 + 9 + 9 + 9.
Let's do the math:
- 9 + 9 = 18
- 18 + 9 = 27
- 27 + 9 = 36
So, 9 • 4 equals 36. This is a basic multiplication concept that is foundational in math.
