It's A. If U=16, 6+10=16
and if you plug in the numbers for the second equation it's 36=2(10)+16
Equation is 112= 14x
x= 8

Answer:
(x +4)^2 + (y-2)^2 = 16
Step-by-step explanation:
We can write the equation for a circle with the formula
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
We know the center is at (-4,2) and the radius is 4
(x- -4)^2 + (y-2)^2 = 4^2
(x +4)^2 + (y-2)^2 = 16
It's 8x + 16y/2 + 4x - 4y :))
