Answer:
9 white ribbons were awarded
Step-by-step explanation:
make white x
make blue b and make red r
b=x-1
r=x+3
w=x
add them up
x-1+x+3+x=29
x-1 +x+3 is 2x+2
2x+2+x=29
3x+2=29
subtract 2 on both sides
3x=27
divide by 2
x=9

Yes!
Answer:
Temperature.
Step-by-step explanation:
Temperature is a measure of the average kinetic energy of all the molecules in a gas. As the temperature, and therefore kinetic energy, of a gas changes the RMS speed of the gas molecules also changes. The RMS speed of the molecules is defined as the square root of the average of each individual velocity squared.
All you need to do is subtract the expressions of the two functions:
![(f-g)(x) := f(x)-g(x)](https://tex.z-dn.net/?f=%28f-g%29%28x%29%20%3A%3D%20f%28x%29-g%28x%29)
So, in your case, we have
![(f-g)(x) := f(x)-g(x) = 3x^2-2x+4 - (5x^2+6x-8) = -2x^2-8x+12](https://tex.z-dn.net/?f=%28f-g%29%28x%29%20%3A%3D%20f%28x%29-g%28x%29%20%3D%203x%5E2-2x%2B4%20-%20%285x%5E2%2B6x-8%29%20%3D%20-2x%5E2-8x%2B12)
