B. To be careful, use brackets: 10(1*2) + 4x which will be 20 + 40x or as you have it, 10*2 + 40x.
Answer:
(x+9)^2 + ( y-2) ^2 = 25
Step-by-step explanation:
The equation of a circle can be written as
(x-h)^2 + ( y-k) ^2 = r^2 where ( h,k) is the center and r is the radius
(x--9)^2 + ( y-2) ^2 = 5^2
(x+9)^2 + ( y-2) ^2 = 25
The answer would be a^9 (a to the ninth power) because you would add the exponents.
