Answer:
The polynomial 3x² + x - 6x + 3 is a prime polynomial
How to determine the prime polynomial?
For a polynomial to be prime, it means that the polynomial cannot be divided into factors
From the list of options, the polynomial (D) is prime, and the proof is as follows:
We have:
3x² + x - 6x + 3
From the graph of the polynomial (see attachment), we can see that the function does not cross the x-axis.
Hence, the polynomial 3x² + x - 6x + 3 is a prime polynomial

Step-by-step explanation:
Answer:
7 groups, 3 boys and 8 girls
Step-by-step explanation:
Let total number of groups be ![x](https://tex.z-dn.net/?f=x)
and total hikers in one group be ![y](https://tex.z-dn.net/?f=y)
if number of girls and boys in every group is same, then
![\frac{21}{x} + \frac{56}{x} = y](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7Bx%7D%20%2B%20%5Cfrac%7B56%7D%7Bx%7D%20%3D%20y)
....(1)
from (1)
will either be 11 or 7
for
the values won't be real.
For ![x = 7\\y = \frac{77}{7} \\y = 11](https://tex.z-dn.net/?f=x%20%3D%207%5C%5Cy%20%3D%20%5Cfrac%7B77%7D%7B7%7D%20%5C%5Cy%20%3D%2011)
so there will be 7 groups with 11 hikers in each groups and every group will have
boys and
girls
