Answer:
x = 4 ±9i
Step-by-step explanation:
x^2 - 8x + 97 = 0
Complete the square by subtracting 97 from each side
x^2 - 8x =- 97
Take the coefficient of x
-8 and divide by 2
-8/2 = -4
Then square it
(-4)^2 = 16
Add it to each side
x^2 - 8x + 16 = -97+16
(x-4)^2 = -81
Take the square root of each side
x-4 = ±sqrt(-81)
x-4 = ±9i
Add 4 to each side
x = 4 ±9i
Two events are mutually exclusive if they cannot occur in the same trial of an experiment.
Answer:
The following shape is not a rectangle, but a square. I know this because the length and width are the same amount of square inch(feet, what ever the square counts for on your graph.) and rectangles width are typically longer than their length. However a square shares the same length and width,
Step-by-step explanation:
Hello,
The correct answer is 5 Liters.
2 Liters of water = 2000 Milliliters.
If she drinks 400 Milliliters per hour, then you do 2000 ÷ 400 to work out the number of hours.
2000 ÷ 400 = 5
Hope this helps!!!! :)
