Answer:
3x
Explanation:
To answer this question, we have to understand what a product is. A product is the result of multiplication. For example, the product of 5 and 5 is 25 because 5 × 5 = 25.
We can apply this concept to the given expression.
"the product of 3 and a number"
means:
3 × "a number"
And since the problem specifies that "a number" is represented by the variable x, we can replace it with that.
3 × x
This looks a bit confusing with the x-like multiplication sign, so we can remove that and make 3 a coefficient of x.
3x
