Can someone help me with this?

Mathematics
1 answer:
liubo4ka [24]3 years ago
7 0

Answer:

A, B and D

Step-by-step explanation:

√5 x √5 x √4 is basically 5 x 5 x 4 = 100, but the 100 still has the root sign

The sqrt of 100 is 10, since 10 x 10 = 100

Like said on the first line, it makes √100 and this is valid since the question does not say to simplify it

24 out of the 30 students in
kirill115 [55]
So if 24 out of the 30 kids rode the bus to school, that means that only six kids did not ride the bus.
We can set up a fraction with this situation! The denominator will be 30 because that is the total amount of kids overall.
Since we are trying to find the number of kids who DID NOT ride the bust, we have to subtract 30 from 24(30-24) to get how many kids did not take the bus.
This would give us a fraction of 6/24. Then we have to simplify it. It can be divided by 6 to the numerator and denominator giving us
1/4

The answer is 1/4 of students did not ride the bus.

Can I get true brainliest or a heart? Thanks, if you need more help please contact me in instagram.

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.
