Answer:
(m - n ) = b
mn = c
The relationship between m and n is such that their product is c and their difference is b
Step-by-step explanation:
roots are x = -m and x = n
-m = -b/2 - root(b*b + 4c)/2
n = -b/2 + root(b*b + 4c)/2
(x + m)(x -n) = x*x +(m - n)x - mn
(m - n ) = b
mn = c
Answer:
$44.15 spend by tyrell if he buys the regular school lunch 9 days and buys ala carte 4 days .
Step-by-step explanation:
As given
