Multiple Choice

Convert the polar equation to rectangular coordinates. $r+ \cos \theta = 3$

• A) \(\left( x ^ { 2 } + y ^ { 2 } - 3 x \right) ^ { 2 } = 9 \left( x ^ { 2 } + y ^ { 2 } \right)\)
• B) \(x ^ { 2 } + y ^ { 2 } = 9 ( x + y )\)
• C) \(\left( x ^ { 2 } + y ^ { 2 } - x \right) ^ { 2 } = 3 \left( x ^ { 2 } - y ^ { 2 } \right)\)
• D) \(\left( x ^ { 2 } + y ^ { 2 } + 2 x \right) ^ { 2 } = 3 ( x + y )\)
• E)none of these
