Classify each polynomial by its degree and number of terms

You have that:

 1) 7x/4+3 (Name using degree: First degree polynomial),(Name using number of terms:binomial)

 2) 5.2x^2-4x+2.5 (Name using degree: Quadratic polynomial),(Name using number of terms:trinomial)

 3) 3/5 (Name using degree: zero degree polynomial),(Name using number of terms:monomial)

 4) 0.75x^2 (Name using degree: Quadratic degree polynomial),(Name using number of terms:monomial).

The answer is $9.90 with rounding to the nearest tenth
