Question 19 (5 points)
What's the standard equation of the circle with the general equation x2 + y2 + 4x – 2y – 20 = 0?
Question 19 options:

1)

(x + 1)2 + (y – 2)2 = 5

2)

(x + 2)2 + (y – 1)2 = 25

3)

(x – 2)2 + (y + 1)2 = 25

4)

(x + 2)2 + (y – 1)2 = 5

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
