Answer:
Step-by-step explanation:
To find the real zeros you must match the function to zero and factor the expression.
We have a polynomial of degree 3.
We try to group the terms to perform the factorization
Now we take (x + 4) as a common factor
If we have an expression of the form we know that this expression is equivalent to:
In this case
So:
Finally:
The solutions are:
Well, the formula for simple interest is
"I" is interest, "p" is the principal, "r" is the rate, and "t" is the time.
If you substitute the numbers, you get
When you multiply them together, you get
So, the simple interest for 3.5 years is $210.
But, in order to get the total balance, you have to add the interest and the principal together.
So, the balance after 3.5 years is $1,210.
