or 
In this problem we have
For
-----> 
so
Find the value of k

substitute the value of x and f(x)


therefore
the equation is equal to

For
-------> substitute in the equation and find the value of f(x)

Answer:
6:3
Step-by-step explanation:
Well all u have to do is 156%*70= 109.2 so N= 109.2
Step-by-step explanation:
x³ + 4x² + 5x + 20
x² (x + 4) + 5 (x + 4)
(x² + 5) (x + 4)
11,15,19,23
an = 11 + 4(n-1)
an = 11 + 4n - 4
an = 4n + 7
