Question: Select all that apply. $$3x$$ - trinomial - monomial - polynomial - none of these - binomial

Select all that apply.

$$3x$$

• trinomial
• monomial
• polynomial
• none of these
• binomial

Solution

The expression \(3x\) is given. A monomial is an algebraic expression consisting of one term. Since \(3x\) has one term, it is a monomial. A polynomial is an expression with one or more terms. Since a monomial is a type of polynomial, \(3x\) is also a polynomial. A binomial has exactly two terms, and a trinomial has exactly three terms. Since \(3x\) has only one term, it is neither a binomial nor a trinomial. Therefore, the correct options are: - Monomial - Polynomial
