​

Answer 1

Answer:

So, 3x, 5y and 3 are the three different terms of the expression. Hence, there are three terms in the provided expression. Note: You may note that in the initial expression it looks like there are four terms present there. But as you can see that two of them have the same variable x and that is why they can be added.
