Answer:
\frac{d}{dx}\left(\frac{1+x^4+x^6}{x^2+x+1}\right)=\frac{4x^7+5x^6+8x^5+3x^4+4x^3-2x-1}{\left(x^2+x+1\right)^2}
Step-by-step explanation:
Not sure but i guess 25 %ile is 55/4=13.75 and 80%ile=80*55/100=44
The answer is A because all three of them have the same amount of coins
I + 6 = r
4r = s
i + r + s = 126
4i + 24 = 4r
s= 4r
i = r-6
4i+24=i+6
-3i=18
i = 6
Solve the rest
You can because you already know the number is 3 and the blank number is n
