Answer: 1
Step-by-step explanation:
3(x-1)
3 times x = 3x
3 times -1 = -3
3x-3

Answer:
(x+8)^2+y^2=16
Step-by-step explanation:
The equation for a circle in center-radius form is
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center and r is the radius.
We are given the diameter is 8 so the radius is 8/2=4.
We are also given (h,k) is (-8,0).
The equation for the circle is
(x--8)^2+(y-0)^2=4^2
(x+8)^2+y^2=16
5 inches because all lines/sides on a square are equivalent.
hope this helps! :)
