Answer:
; 
Step-by-step explanation:
I have never done a problem like this, so this is my first time attempting it.
The standard form for the equation of a circle is:

Begin by grouping the 'x' terms and 'y' terms:

Complete the square for the second polynomial:





Do the exact same process with the other polynomial:

Complete the square:





Bring the 121 to the other side to get:


The above expression is the equation of our circle in standard form. It is centered at the coordinates (7, -2) and has a radius of 11 units. The area of a circle if given by:

1.x^2 +6x - 4 = 6x
X^2 + 6x -4 - 6x = 0
X^2 - 4 = 0
By difference of two squares :
X^2 - 4 = 0 can be written as (x-2) (x+2) = 0
(X-2)=0 therefore x= 2
(X+2)=0 therefore x= -2
2. X^2 - 8x = -6x
X^2 -8x + 6x = 0
X^2 - 2x = 0
X(X-2) = 0
X= 0, X= 2
Answer:
Solve for K by simplifying both sides of the inequality, then isolating the variable.
Inequality Form:
k > 1

(1, ∞)
Step-by-step explanation:
The value of x is 125 degrees from the given diagram
<h3>Lines and angle</h3>
Find the diagram attached
From the diagram, we can see that line l is parallel to line m, hence we can conclude that:
x = 125 degrees (The angles are corresponding angles)
Hence the value of x is 125 degrees from the given diagram
