Answer:
The answer to your question is (x + 3)² + (y + 6)² = 2
Step-by-step explanation:
Endpoints (-4, -7) and (-2, -5)
Process
1.- Find the length of the radius
d =
d =
d =
d =
d =
Radius = =
2.- Find the center
Xm =
Ym =
Center = (-3, -6)
3.- Write the equation
(x - h)² + (y - k)² = r²
(x + 3)² + (y + 6)² = ()²
(x + 3)² + (y + 6)² = 2
Answer:
Option d is correct.
Equation : P=7n+20.
Explanation;
Given the perimeter of each figure is;
Perimeter of triangle is equal to the sum of all the sides of a triangle.
Perimeter of 1 triangle is 21
Perimeter of 2 triangle is 34 and
Perimeter of 3 triangle is 41
Let n be the number of figure and P be the perimeter of the figure;
the only equation which satisfy the given perimeter is;
Check:
for n =1 which means 1 triangle then;
for n = 2 , [ i.e 2 triangle]
and for n =3 [i.e, 3 triangles]
Therefore, the equation P =7n+20 relates the number of triangles in the figure(n) to the perimeter of the figure(P).
