Which statement shows how two polynomials 3x + 6 and 5x2 − 4x demonstrate the closure property when multiplied?

a: 15x3 + 18x2 − 24x may or may not be a polynomial
b: 15x3 + 18x2 − 24x is a polynomial
c: 15x3 + 42x2 − 24x may or may not be a polynomial
d: 15x3 + 42x2 − 24x is a polynomial

is a polynomial.

B is correct

Step-by-step explanation:

Given: and

There are two polynomial with each has two term.

Using closure property multiplied both polynomial.

Product of and

Combine the like terms

This is a polynomial with degree 3

Hence, The product of and is a polynomial.
