Since 6 is positive, it's (x+blank)^2

6/2=3, and (x+3)^2 = x^2+6x+9. We have x^2+6x-2, so we have to add 9 to both sides to get (x+3)^2-2=9, then subtract 9 from both sides to get
(x+3)^2-11=0, or (x+3)^2=11. Square root both sides to get x+3=sqrt(11), and x=sqrt(11)-3, which is approximately 0.32

Sami opens an account with a principal balance of $3,200. The
alina1380 [7]

Answer:

$835.71

Step-by-step explanation:

To solve this problem, we will use the compound interest formula:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

First, lets change 4.75% into a decimal:

4.75% -> \frac{4.75}{100} -> 0.0475

Now, plug the values into the equation:

A=3,200(1+\frac{0.0475}{1})^{1(5)}

A=4,035.71

Lastly, subtract <em>A </em>from the principal:

4,035.71 - 3,200 = 835.71

The interest earned is $835.71
