Question

any one help me question 4 and 5 bta dijiye ​

Answer 1

Answer of question 4

Distance Formula:

\begin{gathered}\sqrt{ {(x_{2} - x_{1})}^{2} + ( {y_{2} - y_{1})}^{2} } \\ \\\end{gathered}(x2−x1)2+(y2−y1)2

let A (x,y) B(-3,0)

\begin{gathered}AB = \sqrt{ {(x + 3)}^{2} + {y}^{2} } = 4 \\ \\ {x}^{2} + {y}^{2} + 9 + 6x = 16 \\ \\ {x}^{2} + {y}^{2} + 6x = 7 ..eq1\\ \\\end{gathered}AB=(x+3)2+y2=4x2+y2+9+6x=16x2+y2+6x=7..eq1
