Step-by-step explanation:
after 5 seconds
it is the answer
The intercepts of the third degree polynomial corresponds to the zeros of the equation
y = d*(x-a)*(x-b)(x-c)
Where a, b and c are the roots of the polynomial and d an adjustment coefficient.
y = d*(x+2)*(x)*(x-3)
Lets assume d = 1, and we get
y = (x+2)*(x)*(x-3) = x^3 - x^2 - 6x
We graph the equation in the attached file.
39.277 is how long the border is
Ralph (r): a + 5
Alphonse (a): a
Ralph + Alphonse = Total
(a + 5) + (a) = 73
2a + 5 = 73
2a = 68
a = 34
Ralph: a + 5 = 34 + 5 = 39
Answer: Ralph has 39 marbles, Alphonse has 34 marbles
