Because the product of two polynomials is always another polynomial, the polynomials are said to be Answerunder the operation of multiplication.

Step-by-step explanation:

Because the product of two polynomials is always another polynomial, the polynomials are said to be closed under the operation of multiplication.

The product of two polynomials is always another polynomial.

When two polynomials are multiplied, each and every term of the first polynomial is multiplied by each and every term of the second polynomial.

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
