There will be infinite answers for x if the equation if the same on both sides, so c=5
You want to put this in the form (x+b)^2 + c
To do this take half of the coefficient of b from the ordinal form which is 6/2=3 as use this as your new b
This give you (x+3)^2.
If you foil this out you get x^2 +6x +9 so you have added 9 to the original expression so now all you need to do is subtract 9 to keep things balanced
The final expression then is (x+3)^2 -9
<u> So c= -9</u>
The inequality which represents possible values of the expression 2+sqrt 10 by virtue of the given inequality; 3.1 < sqrt 10 < 3.2 as in the task content is; 5.1 < 2 + sqrt 10 < 5.2.
<h3>Which inequality correctly expresses the possible values of the expression; 2 + √10 as required in the task content?</h3>
It follows from the task content that the expression given is;
3.1 < sqrt 10 < 3.2
Since the given premises is an inequality, it follows that adding the same number to all parts of the inequality stills holds the inequality true.
Hence by adding 2 to all parts of the inequality, we have;
2 + 3.1 < 2 + sqrt 10 < 2 + 3.2
Therefore, we have;
5.1 < 2 + sqrt 10 < 5.2
Ultimately, 5.1 < 2 + sqrt 10 < 5.2 represent the possible values of the expression 2+sqrt 10 as given by the inequality 3.1 < sqrt 10 < 3.2.

The answer is C.
If we square both sides of the equation, we can rid of the exponent on the right side and add a square root to x + 4
Answer:
Ф=144
Ф =s/r ( Ф is the central angle,s is the arc length, r is the radius)
find r:
radius =circumference/2π=1/2π=0.16
Ф=(2/5) /(1/2π)=4π/5=144 degree (π=180)
Ф in degrees: 144 degrees
