Answer:
He can run 7 miles in 1 hour
Step-by-step explanation:
Let's find how much he can run in 1/4 hour. To do this we divide 5 1/4 by 3
5 1/4 miles divided by 3 = 7/4 miles
He can run 7/4 miles in 1/4 hour
Since 1 hour is 1/4 hour * 4 we can multiply 7/4*4 to get how far he can run in an hour.
7/4*4=7 miles
2100 + 809 equals to 2909.
So Henry and Saul live 14 miles apart and Clair and Saul live 20 miles apart, that it's really, unless there is more to go off of here
I'm assuming that there is another root which should be -SQRT(11)
f(x) = x(x-4)(x+SQRT(11))(x-SQRT(11)
Then
f(x) = x^4 -4x^3 - 11x^2 +44x

Answer:
f(x) = 2(x +2)^2(x -5)
Step-by-step explanation:
The root at x=-2 has even multiplicity. The curve is not flat there, so the multiplicity is 2, not higher. The root at x=5 has multiplicity 1. Then the factored form of this cubic is ...
f(x) = a(x +2)^2·(x -5)
The local minimum when a=1 is about -50, so we judge the leading coefficient to be 2. The desired function is ...
f(x) = 2(x +2)^2(x -5)
