 5            32       3
------- = ------ * -----
 8              5       8                 Reduce that 32/8:  obtain 4.

 3

VMariaS [17]

Answer:

Second option is the correct answer

(x+11)^2+(y+6)^2 = 324

Step-by-step explanation:

x^{2} +12y+22x+y^2-167=0\\x^{2}+22x +y^2 +12y-167=0\\(x^{2}+22x +121)-121 +(y^2 +12y+36)-36-167=0\\(x+11)^2+(y+6)^2-324 = 0\\\huge\red{\boxed{(x+11)^2+(y+6)^2 = 324}}\\
