The player to correctly answer the questions the fastest wins that round and can move on to the grand prize. For the grand prize, Ron must select a box with cash it in. There are 5 boxes to pick from and only one box has money. What are the odds that Ron will win the grand prize?

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road

it is c!

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
