Answer:
X²+y²+2x-10y+18=0 is the equation of circle
Step-by-step explanation:
Eqn of circle is: (x-h) ²+(y-k)²=r²
At (h, k) =(-1,5) and r=8 where h, k are center and r is radius.
Eqn is :(x+1)²+(y-5)²=8²
Or, x²+2x+1+y²-10y+25=8
Or, x²+y²+2x-10y+18=0 is the equation of circle

Answer:
A.
Step-by-step explanation:
81 - 49y^2 = (9 - 7y)(9 + 7y)
FOIL the equation.
(9 - 7y)(9 + 7y)
81 + 63y - 63y - 49y^2
81 - 49y^2
