Answer:
k = - 6
Step-by-step explanation:
Since (x - 2) is a factor then x = 2 is a root
Substitute x = 2 into the polynomial and equate to zero, that is
2³ + k(2)² + 12(2) - 8 = 0
8 + 4k + 24 - 8 = 0
4k + 24 = 0 ( subtract 24 from both sides )
4k = - 24 ( divide both sides by 4 )
k = - 6
Answer:
1/2 person
Step-by-step explanation:
We can use a ratio to solve
6 rolls 1 roll
------------ = -------------
3 people x people
Using cross products
6x =3
Divide each side by 6
6x/6 = 3/6
x = 1/2
1 roll will solve 1/2 person
