Which statement justifies that 3x2 − x − 5 multiplied by 2x2 − x − 3 obeys the closure property of multiplication? the result 6x4 + x2 + 15 has a degree of 4. the result 6x4 + x2 + 15 is a trinomial. the result 6x4 − 5x3 − 18x2 + 8x + 15 is a polynomial. the result 6x4 − 5x3 − 18x2 + 8x + 15 has a degree of 4.

Option C is correct.

Step-by-step explanation:

Given Polynomials: 3x² - x - 5   and 2x² - x - 3

Closure property of multiplication.

States that if two polynomial multiplies then the result we get also is a polynomial.

So, first we find product of given polynomials.

( 3x² - x - 5 ) × ( 2x² - x - 3 )

= 3x² × ( 2x² - x - 3 ) - x × ( 2x² - x - 3 ) - 5 × ( 2x² - x - 3 )

Therefore, Option C is correct.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
