Answer:

Three variable terms

Step-by-step explanation:

The given expression is:

\(3x^3y+5x^2+y+9\)

Since, x and y are the variables in the given above expression, therefore the terms that consists of these variables are known as variable terms, therefore the terms consisting these variables are:

\(3x^3y, 5x^2 and y\)

Thus, there are three variable terms in the given expression.
