Answer:
80%
Step-by-step explanation:
I'm assuming you want the average of the class.
62 + 78 + 83 + 84 + 93
= 400
400/5
= 80
Therefore Victor's overall test score is 80%
To find the other factor you just divide the first factor by the area and you get (x-6)
And you can check by multiplying both the factors by each other.
(X+8)(X-6)
x^2+2x-48

Answer:
BABE JUST USE A CSLCULATOR!! :)
Step-by-step explanation:
The domain of a function contains the x-values of the function while the range of the function contains the y-values of the function. In this case, we substitute 25 and 64 to y. Then,
25 = k2 + 2 k + 1 (k-4) * (k+6) = 0
64 = k2 + 2 k + 1 (k-7) * (k+9) = 0
hence the domain is {-9,-6, 4,7}
