Which one of the following is not closed under the operation being performed

Sergeu [11.5K]

Remember that polynomials are closed under addition, subtraction, and multiplication, but they are not closed under division. The only division you have there is B; therefore the correct answer is B.

A. $(14x-2)3(x-2)=14 x^{2} -90x+10$ . The result is still a polynomial; therefore, answer A is incorrect.

B. $\frac{(14x-2)}{3(x-2)} = \frac{14}{3}$ with a remainder of 26. The result is not a polynomial anymore; therefore, B is the correct answer.

C. $(14x-2)+3(x+2)=17x+4$ . The result is still a polynomial; therefore, answer C is incorrect.

D. $(14x-2)+3(x+2)=17x+4$ . The result is still a polynomial; therefore, answer D is incorrect.

4 1/2 divided by 3/4

Anton [14]

Answer:

Step-by-step explanation:

First, change 4 1/2 into a fraction.

$4\frac{1}{2} \div \dfrac{3}{4} =$

$= \dfrac{4 \times 2 + 1}{2} \div \dfrac{3}{4}$

$= \dfrac{9}{2} \div \dfrac{3}{4}$

$= \dfrac{9}{2} \times \dfrac{4}{3}$

$= \dfrac{9 \times 4}{2 \times 3}$

$= \dfrac{3 \times 3 \times 2 \times 2}{2 \times 3}$

$= 3 \times 2$

$= 6$

Svet_ta [14]

Answer:

Step-by-step explanation:

Rise over run. Difference in y values is rise. 4.25 -6 is -1.75. Run s difference in x values. 12.5 -7 is 5. Divide -1.75/5 to get -0.35 As a faction thats -7/20
