D=√((x2-x1)²+(y2-y1)²)
D=√((x2-x1)²+(y2-y1)²) = √(3-(-3))²+(-2-2)²) = √(6² + 4²)=√(36+16)=√52
D=2√13≈7.21
Q5/2 is what you're looking for
Answer:
the third one
the line extends in both ways forever
<span> Suppose the # of litres in the small container is 'x'.
This would make '2x' litres of water in the larger container.
After taking 8 litres from both containers, the following equation can be written:
(2x-8) = 3 (x-8)
Open the brackets:
2x-8 = 3x-24
Collect like terms:
x = 16
There were 16 litres in the smaller container</span>
