Answer:
x=4+√73 or x=4−√73
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x^2−8x−48=9
Step 2: Add 48 to both sides.
x^2−8x−48+48=9+48
x^2−8x=57
Step 3: The coefficient of -8x is -8. Let b=-8. Then we need to add (b/2)^2=16 to both sides to complete the square.
Add 16 to both sides.
x^2−8x+16=57+16
x^2−8x+16=73
Step 4: Factor left side.
(x−4)^2=73
Step 5: Take the square root.
x−4=±√73
Step 6: Add 4 to both sides.
x−4+4=4±√73
x=4±√73
x=4+√73 or x=4−√73
Answer:
x=4+√73 or x=4−√73
If this answer helped you, I would greatly appreciate it if you gave me brainliest :D.
A parallel line must have the same slope. The only one it can be is A
You have been given the information
2 hour per week
8 week period
So, to find out how many hours of television you can watch, multiply 8 by 2 = 16 hours of television in a 8 week period.
Hope this helps!!
Answer:
42.8 degrees Fahrenheit
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
So we have a 45-45-90 triangle.
This is a special right triangle. In a 45-45-90 triangle, the side lengths are x, and the hypotenuse will be x√2
Since the hypotenuse is 3, we can set it equal to x√2 to solve for x. Therefore:
Divide both sides by √2:
Rationalize:
Our answer is B.
