Answer:
(x - 4)^2 + (y - 6)^2 = 100
Answer: $3,484 <em>(I hope this is the correct way to do it)</em>
Step-by-step explanation:
The formula is: 
- SI = simple interest
- P = principal amount = $13,400
- R = interest rate (in percentage) =
% = 6.5% - T = time duration (in years) = 4 years
<em>If you want to find the total amount, add the principle amount and the interest.</em>

You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:
a² = b²+c²
As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:
b = √(a²-c²) b = √(10²-4²) b = 9.16
With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10
4x dollars left bc 2.5x -3= 5.5 plus 1.5x plus 4=5.5 and together they equal to 11 and 15-11=4
