Which statement justifies that 3x2 − 2x − 4 multiplied by 2x2 + x − 3 obeys the closure property of multiplication? the result 6x4 − 2x2 + 12 has a degree of 4. the result 6x4 − 2x2 + 12 is a trinomial. the result 6x4 − x3 − 19x2 + 2x + 12 is a polynomial. the result 6x4 − x3 − 19x2 + 2x + 12 has a degree of 4. i think it is b.

We have been given two polynomials

Let us first multiply these polynomials.

Now, we know that polynomials follows closure property of multiplication.

It means that when we multiply two polynomials, the result will be a polynomial.

Since, when we multiplied the given polynomials, we got which is a polynomial.

Therefore, the correct option is

The result   is a polynomial.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
