Answer:
A. There are four terms.
C. The term [tex]\frac{30}{y}[/tex] is a ratio.
Step-by-step explanation:
The expression given is the sum of four components: a third order monomial ([tex]4\cdot x^{3}[/tex]), a second order monomial ([tex]-7\cdot x^{2}[/tex]), a zero order monomial ([tex]15[/tex]) and a ratio ([tex]\frac{30}{y}[/tex]). There are a sum and two differences. Hence, the correct answers are:
A. There are four terms.
C. The term [tex]\frac{30}{y}[/tex] is a ratio.
