1. Remove the parenthesis using the next rules:

2. Start to remove the parentheses from the center to the edges:

<h2>Then, the solution is 8</h2>
Answer:
Step-by-step explanation:
<u><em>Part B:</em></u>
The center of the circumscribed circle around a triangle is equidistant from vertices of that triangle. To find the circumcenter need to draw at least two perpendicular bisectors to the sides of the given triangle. Point of intersect of them is center of the circumscribed circle.
<u><em>Part C:</em></u>
Coordinates of the midpoint of line BC ( y = - 1 ) are
(
,
) = <em>( - 2 , - 1 )</em> and the equation of the line ⊥ to BC is <em>x = - 2</em>
Because BC is ║ to x-axis and m∠A is 90° , the center of the circle is midpoint of BC and r =
= 4
The green triangle is the rotated image PQR. Point of rotation is (1,-1).
The red triangle is the reflected image XYZ. It’s reflected on the x axis
