Answer:
Conner had 225 in the beginning
Step-by-step explanation:
Let lisa's money be L
and Conots money be C
C+L= 360----------------1
Connor gave Lisa 40% of his money,
L= 0.4C+L
C= 0.6C
L=0.4C+L=C
C=0.4C+L---------------2 <em>she had the same amount of money as he did</em>
C-0.4C=L
`0.6C=L
Put L=0.6C in eqn 1
C+0.6C= 360
1.6C= 360
C= 360/1.6
C=225
C+L= 360----------------1
225+L=360
L= 360-225
L= 135

Step-by-step explanation:
The Standard form of the equation of circle is (x+21)² + (y+19)² = 849
<h3>What is Standard form of circle?</h3>
To transform general form to a standard form, you can use completing the square method or you can convert this equation
x² + y² + Dx + Ey + F = 0 to x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0
Here, Given: x² + y² + 42x + 38y − 47 = 0
Required: Find the values of h, k, and r using this formula
x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0
On comparing we get,
-2h = 42
h = 21
-2k = 38
k = 19
-47 = h² + k² - r²
-47 = 21² + 19² - r²
r² = 849
r = √849
Thus, the Standard form of the equation of circle is (x+21)² + (y+19)² = 849
