Answer:
±11.18
Step-by-step explanation:
the function is:

and to find the roots we need to find which values of
makes the function result in zero:

solving for
:

A square root has two solutions, one positive and one negative, so the solutions are:
±
≈ ±11.18
the roots of the quadratic equation are +11.18 and -11.18
To solve x, you would distribute the 3 to the numbers in the parenthesis. 3x-3=5+x Now you would combine like-terms which would give you: 2x=2. Now you would divide by 2 on both sides to give you x=1. I hope you understand what I did. Hope I helped you!
Answer:
1.
( n + 4 ) - 9
- n - 4 - 9
- n - 13
2.
40 = x - 1
- x = - 1 + 40
- x = 39
Step-by-step explanation:
I duno if this is right...
Both values need to be in the same usable form. So, I would convert the two values into minutes. That leaves you 10 minutes of video games and 60 minutes of television. This ratio would be 10/60 or 10:60. Simplified would be 1/6 or 1:6.
