Answer:
-77/13
Distribute 3 to the ones in the parenthisis and do the same to the other side and distribute the negative nine. solve what is left and subtract the two terms and simply solve whats next.
X = - 8 should be the answer
<h3>
Answer:</h3>
x² -6x = -13 ⇒ x ∈ {3-2i, 2+2i}
<h3>
Step-by-step explanation:</h3>
To make a=1, divide the equation by the coefficient of x², which is 8.
... x² -6x = -13 . . . . . . your blanks are filled with -6 and -13
Now, to complete the square, add the square of half the x-coefficient:
... (-6/2)² = 9.
... x² -6x +9 = -4 . . . 9 added to both sides
... (x -3)² = -4 . . . . . rewrite as a square
... x -3 = ±2i . . . . . . take the square root
... x = 3 ±2i . . . . . . . add 3
The solutions are the complex numbers x = 3 ±2i.
X < 31.5
answer is the middle symbol
start at 31.5 (right in the middle between 31 and 32) move open arrow to the left
Answer:
i would say a. or c. because im in tenth grade civics right now and those sound like more political problems than the other ones.
