Answer:
x^2-18x+y^2+18y+137=0
express both x and y term in completed square form
(x-9)^2 -81+(y+9)^2-81+137=0
(x-9)^2+(y+9)^2-25=0
(x-9)^2+(y+9)^2=5^2
here the x coordinate of the centre is +9
y coordinate is -9(the negative value of the value associated with the x and y square brackets)
radius=5
Answer: The first five Multiples of 6 is 6,12,18,24,30.
The first 5 multiples of 8 is 8,16,24,32,40.
Step-by-step explanation:
If you dont know the multiples you can add the number how many times you need to. for example: 5x2. You would add 5+5 and it will equal 10.
