Lamar has been running sprints to prepare him for his next football game. he has found that he can maintain his maximum speed for 45 yards. He thinks of running in a 5 km race in a few months, but he doesn't know if he can maintain his maximum speed for the entire 5 km. ca you help him determine how far he can go

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

52 \43 i don't know this i tried

38 was the other number of your question.
