I believe you meant: Use completing the square to determine the center and radius of the circle represented by this equation: <span>X^2+y^2-10x+6y=15
x^2 - 10x + 25 - 25 + y^2 + 6y + 9 - 9 = 15
Then:
(x-5)^2 + (y+3)^2 = 24 = 2sqrt(6)
This circle is centered at (5,-3) and has radius 2sqrt(6).</span>

Answer:
the answer is B: 4
Step-by-step explanation:
The common factors of 36 and 40 are 1, 2, 4. We can use prime factorization to identify the common factors.
Answer:
28.8
Step-by-step explanation:
the original is 45=100%
it reduced by 36% meaning;100%-36%=64%
if45=100%
? =64%
45*64=2880/100=28.8
