Answer:
k=20
Step-by-step explanation:
when x approaches 4, the denominator x-4 approaches 0
if the denominator is 0, it means that this is invalid
if the function is a number over 0 when x=4, it represents a vertical asymptote, which means no limit
so the only way possible to let there be a limit is to let the function be 0/0 when we plug in x=4
so x^2 + x - k = 0 when x = 4
4^2 + 4 - k = 0 ==> 20 - k = 0 ==> k = 20

Answer:
4/5 of the cattle is left
Step-by-step explanation:
Given,
A farmer sells 2/5 of his cattle
Let "x" be the total number of cattle
Then,
sold = 2 / 5 x
Then,
Remaining = x - 2x / 5
remaining = 3x / 5
He gives 1/3 of the remainder to his son
son = 1 / 3 × 3x / 5
son = x / 5
Then,
Remaining = 3x / 5 - x / 5
Remaining = 4x / 5
Hope this answer helps you :)
