Answer:
x^2 -8x -5 = -3
x^2 -8x -2 = 0
We complete the square by:
1) Moving the "non X" term to the right:
x^2 -8x = 2
2) Dividing the equation by the coefficient of X²
The coefficient of x is 1 so we don't do anything
3) Now here's the "completing the square" stage in which we:
• take the coefficient of X
that is -8
• divide it by 2
-8 ÷ 2 = -4
• square that number
-4*-4 = 16
• then add it to both sides of the equation.
x^2 -8x +16 = 2 +16
That becomes
(x -4)^2 = 18
we take the square root of both sides:
(x -4) = sqr root (18)
x1 = sqr root (18) +4
AND
(x+4) = sqr root (18) -4
x1 = sqr root (18) +4 = 4.2426406871 + 4 = 8.2426406871
x2 = sqr root (18) -4 = = 4.2426406871 - 4 = .2426406871

Hello, How are you doing today?
If your friend makes 2$ more than you do, then you must form an equation for the problem. y = amount she has, x = your amount. Therefor, it would be:
y = x + 2
If you make 6 dollars, she will make 8 and so on. Thank you, have a nice day!
Answer:
O is largest, C is medium, and T is smallest
Step-by-step explanation:
You need to pay close attention to the side length. The higher the length, the smaller the angle.
