Answer: 
Step-by-step explanation:
Given the polynomial
, you can evaluate it for the given value of the variable "x" by substituting the value
into the polynomial.
Therefore, when
, you get the following result:

Answer:
$70,201.38
Step-by-step explanation:
To determine the principal amount, we can use the formula:

A = $200,000
r = 7% or 0.07
t = 15 years
n = 12
Now let's substitute our values.



So the principal needed to get 200,000 in 15 years is $70,201.38.
3/10=4/x
3x=10(4)
3x=40
x=13.33
