2/3 because you can divide the top and bottom by 8
Soccer ball reaches its highest position when its equation turns from positive slope to zero and then negative. Mathematically it is where the derivative of the its function equals to zero. so:
d(-3x^2 + 6x + 3) / dx = -6x + 6
-6x + 6 = 0 -> x = 1 ->

it seems Paige's ball reaches higher than Viaola's with only 6 meters height.
Answer:
x=83º
Step-by-step explanation:
The interior angle sum of a Hexagon is 720º
146+169+59+129+134+x=720
x=720-637
x=83
