we have

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares

-----> equation in vertex form
therefore
the answer is the option C

Answer:
A: 180°, semi circle
Step-by-step explanation:
We are told that MK and HL are the diameters.
By Inspection, it is clear that MHK will be a semi circle.
The angle of that chord will be 180° since sum of angles on a straight line is 180°.
Answer is option A
0.49 is the answer because that is <span>the approximate probability</span>
Answer:

Step-by-step explanation:
The base case in the recursive function are:


The recursive case is equal to:

So replace
for
:

In the new expression
is a base case so you don't have to worry for that part, but
is still the recursive case so evaluate again in 

and
are define as base cases so you replace for it's numbers:

Now return to
and replace for the new values:

So the final answer is 20
The answer is D. for sure 21 square inches
