PLZ HELP!!!!!!!!!!!!!!
Vsevolod [243]

Answer:

Isn't that just soild liquid and gas atoms?

The image is showing how the atoms change depending on which state of matter it is, so if it is a soild the atoms would be really compacted as it moves slower, if it's a liquid then it's more looser than a soild, but more compacted than a gas, and a gas is just moving a lot and has a lot more space.

^^ That would be the answer if you on the states of matter or something like that unit.

6

−1

(Divide both sides by -1)

x2=−6

x=±√−6(Take square root)
