Answer:
9-6.92820323i Nothing else can be done.
Step-by-step explanation:
-48 is not a perfect square but 81 is a square. When you try to square -48 it comes to be 6.92820323i.
Vertical angles are congruent, so their measures are equal.
Set the angle measures equal and solve for x.
2x + 2 = 3x - 52
-x = -54
x = 54

The answer is inside a box.
When we multiply a whole number with a fraction, we can think of the whole numbers as "over one"...
5 3 5 15
3 * --- = --- * ---- = ----
6 1 6 6
We can further simplify the fraction, by dividing numerator and denominator by 3...
15 15 / 3 5
--- = ------- = ----
6 6 / 3 2
Since this is an improper fraction, we need to turn it into a mixed number...
5 2 + 2 + 1 2 2 1 1 1
---- = -------------- = --- + ---- + --- = 1 + 1 + ---- = 2 --- or 2.5
2 2 2 2 2 2 2
Answer:
The answers are in the image.
Step-by-step explanation:
Charlie made the mistake by not getting the equation equal to zero.

Subtract 16 to both sides making it equal to 0.

Using Quadratic Formula to Solve for x.
C is 2 because you have to move the 5 so you add 5 to 13 which is 18 then divide both sides by 9 so it's 2
