Final answer:

To solve for x in the pentagon, we rearrange the equation into a quadratic form and use the quadratic formula to find the two possible values of x: 0.0216 or -0.0224.

Step-by-step explanation:

We rearrange this into a quadratic equation that equals 0:

0.000484 -0.00088x = x²x² + 0.00088x -0.000484 = 0
Now we use the quadratic equation to solve for the two possible values of x:

Evaluate for both signs in the numerator-first the + sign and then the - sign:

x = 0.0216 or x = -0.0224
