H + c = 456
c = 3h
h + 3h = 456
4h = 456
h = 456/4
h = 114 <=== hamburgers sold
c = 3h
c = 3(114)
c = 342......cheeseburgers sold
You have 6 left 4×6=24 3/4=18 candy you ate
Answer:
-5, multiplicity 3; +9, multiplicity 2; -1
Step-by-step explanation:
The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.
f(x) = (x+5)^3(x-9)^2(x+1) has roots ...
- -5 with multiplicity 3
- +9 with multiplicity 2
- -1
