<u>Let's first gather all the information we have</u>:
<u>Let's put that into standard form</u>
- (h, k): center's coordinate
- r: radius
<u>To put that equation into general form</u>:
⇒ expand all the quadratics on one side and move the radius squared
to the same side as the quadratics
<u>Answer: x² + y² + 6x - 4y - 12 = 0</u>
<u></u>
Hope that helps!

Answer:
it is 32
Step-by-step explanation:
In this question, Suzan is taking 5 marble from a bag containing 4 red marbles, 3 green ones, 4 white ones, and 3 purple ones. The total marble in the bag should be: 4+3+4+3= 14. The question is how much the probability to get <span>1 red, 2 green, 1 white and 1 purple.
Ways to take 5 marble out of 14=14C5= 14!/5!9!= </span>2002<span>
</span>Ways to take 1 red marble out of 4= 4C1= 4<span>
</span>Ways to take 2 green marble out of 3= 3C2= 3
Ways to take 1 white marble out of 4= 4C1= 4
Ways to take 1 purple marble out of 3= 3C1= 3
Then the probability would be: 4*3*4*3/ 2002= 144/2002= 72/1001
