The equation of a circle:

(h, k) - a coordinates of the center
r - a radius

Answer:
the center: (3, -2)
the radius: 3
R^2=(96/2)^2+14^2
r^2=2500
r=√2500
r=50
Answer:(x+6)(x^2-9)
Step-by-step explanation:
Answer:
The answer is 27
Step-by-step explanation:
The reason being, you can solve this 2 ways.
1) Combine like terms, 7a-4a = 3a.
Now just substitute (a=9) into 3a.
3 * (9) = 27.
2) Or just substitute a = 9 into the original expression.
7 * (9) - 4 * (9)
= 63 - 36 = 27
(mn)3 = 3(mn) = 3 * m * n
so your answer is 3mn
