Answer:
Step-by-step explanation:
x²+y²-2x-10y+1=0
compare with x²+y²+2gx+2fy+c=0
center is (-g,-f)
radius=√(g²+f²-c)
2g=-2
g=-1
2f=-10
f=-5
radius=(1,5)
c=1
let eq. of circle be x²+y²-2x-10y+c=0
∵ it passes through (2,-3)
2²+(-3)²-2(2)-10(-3)+c=0
4+9-4+30+c=0
c=-39
eq. of circle is is x²+y²-2x-10y-39=0
Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v

Step-by-step explanation:
(5x -2y) / y
Let x = -4 and y = -4
(5*-4 - 2*-4) / -4
(-20 +8) / -4
-12/ -4

The area of a square is given by the expression: A = L² <em>(where L is the side length)</em>
<em />
A cube has 6 sides and each side is a square. So the surface area of a cube will be 6x the area of a square of this cube.
<h3>Acube = 6L²</h3>
