First let's get rid of the $d^2$ in the denominator of the fraction on the right side of the equation. This will help to get only $x$ and a coefficient on one side of the equation:

$A = \dfrac{730x}{d^2}$

$d^2A = 730x$

Now, simply divide by 730 to find $x$ :

$d^2A = 730x$

$\boxed{\dfrac{d^2A}{730} = x}$

Percy solved the equation x2 7x 12 = 12. his work is shown below. is percy correct? explain. 1. (x 3)(x 4) = 12 2. x 3 = 12 or x

stepladder [879]

Percy solved the equation by expanding the expression on the left-hand side, and this is incorrect

<h3>How to determine the true solution?</h3>

The equation is given as:

x^2 + 7x + 12 = 12

The first step in solving the equation is to equate the equation to 0.

i.e.

x^2 + 7x + 12 - 12 = 0

This given

x^2 + 7x = 0

From the question, Percy solved the equation by expanding the expression on the left-hand side

Hence, Percy's solution is incorrect
