Answer with explanation:
- Monomial = Polynomial with one term.
- Binomial = Polynomial with two terms.
- Trinomial = Polynomial with three terms.
- Degree - highest power of variable
- Leading coefficient - Coefficient of the variable or variables with highest power.

Name = Binomial (as it has two terms)
Degree= 5 (power of x)
Leading Coefficient = 4 (coefficient of
)

Name = trinomial (as it has 3 terms)
Degree = 3 (highest power of x)
Leading Coefficien= 7 ( coefficient of
)

Name= Monomial (as it has 1 term)
Degree= 5+3+1= 9 [Addition of power of all variables]
Leading Coefficient = 18
