The <em>correct answer</em> is:
B) the point of concurrency of the perpendicular bisectors of the sides of the triangle
Explanation:
The definition of circumcenter is "the point of intersection of the perpendicular bisectors of a triangle."
To construct the circumcenter, we first construct the perpendicular bisector of each side of the triangle. Once we have these three lines, we find their point of intersection; this is the circumcenter.
I don’t know if this would be considered a dance step but an aerial uses your quad because you have to push off your front leg and your hamstring because you have to drive your back leg
Answer:
2(s + 5) = 2s + 10, not 2s - 10
2s - 10 = 2s + 10

y = -(x + 3)² + 1
y = -(x + 3)(x + 3) + 1
y = -(x² + 3x + 3x + 9) + 1
y = -(x² + 6x + 9) + 1
y = -x² - 6x - 9 + 1

or
y = -x² - 6x - 8
y = -(-2)² - 6(-2) - 8
y = -(4) + 12 - 8
y = -4 + 12 - 8
y = 8 - 8
y = 0
