Answer:
4*sqrt(10)
Step-by-step explanation:
For y = 0: 3x = - 12 - - > x = -4, so A(-4,0)
For x=0: y=12, so B(0,12)
The distance between two points is given by:
[tex]d = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} }[/tex]
[tex]d = \sqrt{( - 4 - 0) {}^{2} + {(0 - 12)}^{2} } = 4 \times \sqrt{10} [/tex]
