Hey! When you ask a question there is a math equation option. Use that to scan the problem and it will give you your answer.
Answer:
-2/5
Step-by-step explanation:
p(x) = 5x + 2
plug p(x) = 0
5x + 2 = 0
5x = - 2
x = - 2/5
The final amount of the compound interest after 6 years would be $ 294, 122, 500
<h3>How to determine the final amount</h3>
The formula for the final amount is given as;

Where
A = final amount
P = principal interest
r = interest rate
n = number of times
t = time of periods
We have,
A =

A = 
A =
× 
A =$ 
Thus, the final amount of the compound interest after 6 years would be $ 294, 122, 500
