Half of the perimeter multiplied by the radius of the inscribed circle is formula to find the area of a triangle, by using this you can see that the perimeter is 260 because 2340 / 9 = 260.
Answer:
B: y = 3x + 1
Step-by-step explanation:
The formula to find the rate of change is y2-y1/x2-x1
6-(-4)/-3-(-1)
=10/-2
=-5
The equation of a circle:

(h, k) - center
r - radius
Look at the picture:
center: (4, -2) → h = 4, k = -2
radius: r= 5
Substitute:
