Answer:
c
Step-by-step explanation:
x²+y²+4x+6y=0
compare with x²+y²+2gx+2fy+c=0
centre is (-g,-f)=(-2,-3)
radius=√(g²+f²-c)=√((-2)²+(-3)²-0)=√13
5.96 x 10 2
For A+B
a. 0.3+0.8 = 1.1
b. 1.2+1.4 = 2.6
c. 3.4 + 4.2 = 7.6
d. 2.25 + 2.95 = 5.20
For B-A
a. 0.8-0.3 = 0.5
b. 1.4-1.2 = 0.2
c. 4.2-3.4 = 1.2
d. 2.95-2.25 = .070
