Yes that is correct. hope this helps
You plug in a 3 wherever you see an x
2x^3-4x^2+6x
2(3)^3-3(3)^2+6(3)
2(27)-3(9)+18
54-27+18
27+18
=45

Picture?? This question is incomplete just get a picture then I can answer it
Answer:
1,001 ways for them to decide.
Step-by-step explanation:
The order in which they will visit the countries is not important, so we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
![C_{n,x} = \frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
In this question:
10 countries from a set of 14. So
![C_{14,10} = \frac{14!}{10!(14-10)!} = 1001](https://tex.z-dn.net/?f=C_%7B14%2C10%7D%20%3D%20%5Cfrac%7B14%21%7D%7B10%21%2814-10%29%21%7D%20%3D%201001)
1,001 ways for them to decide.
