Answer:
Step-by-step explanation:
x^2 - 22x = 10
Next step is to complete the square on the left hand side of the equation and it would be balanced by adding the same number to the right side of the equation. It becomes
x^2 - 22x + (22/2)^2 = 10 + (22/2)^2
x^2 - 22x + (11)^2 = 10 + (11)^2
x^2 - 22x + (11)^2 = 10 + 121
x^2 - 22x + (11)^2 = 131
x^2 - 22x + 121^2 = 131
(x - 11)^2 = 131
Taking square root of both the left hand side and the right hand side of the equation, it becomes
x - 11 = ±√131
x - 11 = ±11.45
Adding 11 to the left hand side and the right hand side of the equation, it becomes
x - 11 + 11 = ±11.45 + 11
x = 11.45 + 11 or x = -11.45 + 11
x = 22.45 or x = - 0.45
Answer:
circle
Definition: A circle is the set of all points in a plane that are equidistant from a given point called the center of the circle.
X= -2 + the root of 5
OR
x= -2 - the root of 5
1.
Ratio = 400 : 500
2.
Ratio = 300 : 700
3.
Ratio = 75 : 125
4.
Ratio = 280 : 320
13.
Ratio = 70 : 30 : 20
14.
Ratio = 125 : 150 : 175
15.
Ratio = 125 : 200 : 225
16.
Ratio = 1.98 : 4.62 : 7.26
