Hint: 

They are isosceles triangles

And If you know the measure of one angle, what can you do?

You can also try to find the measures of the two other angles by doing 120/2 which would get you 60 degrees!

Hope this helped!

If you know you posted there, you can go to your profile and see the "answers" page.

This is what I got--

(6x^3*4)+(4x^2*3x)+(-7x*3x^2)+(-5*6x^3)
24+12-21-30 = -15

Therefore, the coefficient would be -15.

Hope this helped!

 

I agree! I think there might be an easier way though....

Yup, and exponential graphs are NEVER linear! Keep this in mind :D

Combinations!! That's it!!! Nice, jfan17.

Just in case you don't know what a combination is, the formula is n!/r!(n-r)!

Hope this helped!

Thanks, even though it was mostly jfan17 :D

Nice, jfan17!!!

Here is a hint to make everything clearer:

Let's say that the people voting are Peoples 1-50.

The candidates are Candidates a-d.

We can draw a diagram to represent this question, or we can find the equation easily, labeling x as the people voting and y as the candidates.

Hope this helped!
