Andrea argues that (5m−3) (2m+4) models the closure property. What reasoning could Andrea use to argue that multiplication of polynomials is closed? (1 point) Responses The coefficients of the product are whole numbers and the product is a polynomial The coefficients of the product are whole numbers and the product is a polynomial The coefficients of the product are integers and the product is a polynomial The coefficients of the product are integers and the product is a polynomial The exponents of the product are whole numbers and the product is a polynomial The exponents of the product are whole numbers and the product is a polynomial The terms in the expression are rational numbers and the product is a polynomial The terms in the expression are rational numbers and the product is a polynomial The exponents of the product are integers and the product is a polynomial The exponents of the product are integers and the product is a polynomial
Andrea could argue that the product of (5m−3) and (2m+4) is a polynomial because the coefficients of the product are integers and the exponents of the product are whole numbers.

Apologies for the repetitive options. Andrea could argue that the product of (5m−3) and (2m+4) is a polynomial because the coefficients of the product are integers and the exponents of the product are integers.
