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 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 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 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 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 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 Question 2 8)

Answer 1

Andrea could argue that the expression (5m−3)(2m+4) models the closure property of multiplication of polynomials because the coefficients of both terms and the product are integers, making it a polynomial expression.
