Answer:
see explanation
Step-by-step explanation:
A monomial is an expression with one term
A binomial is an expression with 2 terms
A trinomial is an expression with 3 terms
Thus
- 2x² - x + 3.5 ← has 3 terms, hence trinomial
10xyz³ ← has 1 term, hence monomial
- x²y² + 2y ← has 2 terms, hence binomial
8x² + 0.25 ← has 2 terms, hence binomial
x³[tex]y^{4}[/tex] + 2x²y - 3x ← has 3 terms, hence trinomial
