Answer:
4n + 4
Step-by-step explanation:
Azhar - n years old now.
Last year he was (n-1).
His mother was 4(n -1) last year.
Now his mother 4(n-1) + 1.
7 years later she will be 4(n - 1) + 1 + 7 = 4n - 4 + 8 = 4n + 4
1 inch = 4 feet
11 inches = 44 feet (multiply both sides by 11)
<h3>
Answer: 44 feet</h3>

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
