Answer:
A. x equals 5 plus or minus the square root of thirty-three all over 2
Step-by-step explanation:
Let's move all the terms to one side:


Now, we want to use the quadratic formula, which states that for a quadratic equation of the form
, the roots can be found with the equation:
or
.
Here, a = 1, b = -5, and c = -2, so plug these in:
OR

Thus, the answer is A.

The option that's true about the plane illustrated is E. None of these.
<h3>How to illustrate the plane?</h3>
From the information given, it should be noted that DBC isn't an isosceles triangle.
Also, from the figure, one can see that DAB isn't similar to DAC.
Likewise, BD and DC aren't perpendicular.
In conclusion, the correct option is E.

If we take the equation and multiply out the left side, we get....

+ 2xk +

=

+ x +

The x^2 and k^2 cancel out on both sides leaving us with this...
2kx = x
If we divide both sides by 2x to isolate k,
k ends up = 1/2
