18z 2+17z+4
Step-by-step explanation:
it hard try to give more point
If youre a cashier
if youre a mathematician
if you have to pay taxes and bills
if your have to loan something
The factors include 1,2,4,5,8,10,20,40.
X2+5x+y2-y=-2
X2+2*5x2+(5/2)^2-(5/2)^2+y2-2*y/2+(1/2)^2-(1/2)^2=-2
(x+5/2)^2+(y-1/2)^2-13/2=-2
(x+5/2)^2+(y-1/2)^2=9/2
So centre =(-5/2,1/2)
Radius=(9/2)^(1/2)
