Which statement is true about the polynomial
–3x4y3 + 8xy5 – 3 + 18x3y4 – 3xy5 after it has been fully simplified?

it has 3 terms and a degree of 5.
it has 3 terms and a degree of 7.
it has 4 terms and a degree of 5.
it has 4 terms and a degree of 7.

The correct answer among the choices given is the last option. When it has been simplified, it has 4 terms and a degree of 7. For polynomials having to or more variables, degree can be of a term or of the polynomial. The degree of a term is the sum of the exponents in a specific term.

 –3x^4y^3 + 8xy^5 – 3 + 18x^3y^4 – 3xy^5
 –3x^4y^3 + 5xy^5 – 3 + 18x^3y^4
