The equation of a circle is (x-h)²+(y-k)²=r², (h,k) is the center of the circle, r is the radius.
in this case, if the radius is √5, the equation is (x+9)²+(y+4)²=5

State if the three side lengths 3 mi, 12 mi, 13 mi?
marusya05 [52]

Since the sum of any two sides is greater than the third, hence the three sides for the sides of a triangle

<h3>What is a triangle?</h3>

A triangle is a 2-D shape with 3sides and angles. According to the question, we are to determine whether the given measures form sides of a triangle.

For the following measure to form the sides of a triangle, the sum of any two sides must be equal to the third as shown:

3 + 12  = 15 > 13

3 + 13 = 16 > 12

13 + 12 = 25 > 3

Since the sum of any two sides is greater than the third, hence the three sides for the sides of a triangle
