I would immediately reduce this by div. every term by -2:
x^2 + 8x + 22 = 0
Next, I'd "complete the square:"
x^2 + 8x + (4)^2 - (4)^2 + 22 = 0
(x + 4)^2 - 16 + 22 = 0, so that (x+4)^2 + 4 = 0.
Then sqrt( (x+4)^2 = sqrt(-4)
x+4 = plus or minus i*2
x = -4 plus or minus i*2 (answer)

<em>*Split the shape into 3 rectangles.</em>
<u>Rectangle 1:</u> 4 x 4 x 8 = 128
<u>Rectangle 2:</u> 14 x 4 x 4 = 224
<u>Rectangle 3:</u> 4 x 4 x 8 = 128
<u>Total:</u> 128 + 224 + 128 = 480 cm³
Hello!
In a taxi cab, the longer you ride, the more it costs. This would make a scatter plot go through Quadrant 1.
Therefore, it would have a positive relationship
I hope this helps!
Answer:
