The triangle ABC and the triangle BDA are similar, therefore:
This is the standard form equation 
What is the ellipse?
The equation for an ellipse is typically written as x² a² + y² b² = 1. x² a² + y² b² = 1. An ellipse with its origin at the center is defined by this equation. The ellipse is stretched further in both the horizontal and vertical directions if a > b, a > b, and if b > a, b > a, respectively.
The standard form of the equation of an ellipse with center (h, k)and major axis parallel to the x-axis is:

where,
a > b
the length of the major axis is 2a
the coordinates of the vertices are (h±a,k)
the length of the minor axis is 2b
the coordinates of the co-vertices are (h,k±b)
the coordinates of the foci are (h±c,k),
where c² = a² − b².
so,

Hence, this is the standard form equation

Answer:
-34.64
Step-by-step explanation:
-20.3-14.34
-34.64
First you must find the rate of both taxes. Since its 8% and 6%, you must add them both together, then divide them by 100.
14/100 = .14
Then for both rates you must add 1 because it is a tax increase.
1 + .14 = 1.14
Finally times 37.50 with 1.14
37.50(1.14) = <span>42.75

<span>$42.75 is the answer.</span>
