Since you want help i wont tell you the answer..just how to solve...
(need to know) Of in math means multiply
they are giving you something to plug in to f(x) so everywhere in the equation there is an X replace with the equation and solve....in this case they are replacing f(x) with f(a+2) so take 3+x and change it to 3+a+2 and then take x-3 and make it a+2-3.
Then you have 3+a+2 divided by a+2-3
(I'll assume that the blank spaces are PLUS signs ( + ),
as they usually are on Brainly.)
The mystery complex number is (5 - i) .
(3 + 2i) x (5 - i) = (17 + 7i)
FOIL it out and you'll see it.
Answer:
The radius is r=5 units
Step-by-step explanation:
we know that
The equation of the circle in standard form is equal to
![(x-h)^{2}+(y-k)^{2}=r^{2}](https://tex.z-dn.net/?f=%28x-h%29%5E%7B2%7D%2B%28y-k%29%5E%7B2%7D%3Dr%5E%7B2%7D)
where
(h,k) is the center and r is the radius
we have
![x^{2}+y^{2}-12x+6y+20=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%2By%5E%7B2%7D-12x%2B6y%2B20%3D0)
Convert to standard form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
![(x^{2}-12x)+(y^{2}+6y)=-20](https://tex.z-dn.net/?f=%28x%5E%7B2%7D-12x%29%2B%28y%5E%7B2%7D%2B6y%29%3D-20)
Complete the square twice. Remember to balance the equation by adding the same constants to each side
![(x^{2}-12x+36)+(y^{2}+6y+9)=-20+36+9](https://tex.z-dn.net/?f=%28x%5E%7B2%7D-12x%2B36%29%2B%28y%5E%7B2%7D%2B6y%2B9%29%3D-20%2B36%2B9)
![(x^{2}-12x+36)+(y^{2}+6y+9)=25](https://tex.z-dn.net/?f=%28x%5E%7B2%7D-12x%2B36%29%2B%28y%5E%7B2%7D%2B6y%2B9%29%3D25)
Rewrite as perfect squares
![(x-6)^{2}+(y+3)^{2}=5^{2}](https://tex.z-dn.net/?f=%28x-6%29%5E%7B2%7D%2B%28y%2B3%29%5E%7B2%7D%3D5%5E%7B2%7D)
therefore
The center is the point (6,-3) and the radius is r=5 units
