Answer:
Translate circle C 3 units towards the right and 5 units up.
Dilate this translated circle C by a factor 2.5. It will overlap (become congruent to) circle A
This is enough to prove that the two circles are similar
You can do 104 divided by 2 and get 52 and then you can divide it for 2 again and get 26
R2-4r-77 = (r-11)(r+7)
r has to be greater than 11 in order for the formula to represent the area of a rug since a side length cannot be less than or equal to 0.
Answer:
5 units
Step-by-step explanation:
The distance from a point (m, n ) to the line Ax + By + C = 0 is given by
d = 
For the point (- 1, 3 ) , with m = - 1 and n = 3
3x - 4y = 10 ( subtract 10 from both sides )
3x - 4y - 10 = 0
with A = 3 , B = - 4 , C = - 10
d = 
= 
= 
= 
= 5
