A9litre jug is full of water. i have three cups which can hold 7litres, 2litres and 4litres respectively. find a way to pour water from the jug between the cups so that i end up with exactly 3 litres in three of the vessels

Here's a solution in 8 pours. The list here has the form ...

from vessel ⇒ to vessel; (vessel contents for vessels 9, 7, 4, 2)

The starting state is (9, 0, 0, 0).

Steps 6 and 8 can be swapped, as the order in which vessels 9 and 4 are filled to the 3 level doesn't matter.

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
