Answer: 22 neutrons
Explanation: 40 is the mass number = atomic mass = total number of protons and neutrons in atomic nucleus
18 is the number of protons in the nucleus of this atom
Then 40 - 18 = 22 neutrons
and this is Argon
1 is correct, i’m not sure if that’s the answer your looking for because of the wording, but if it’s a multiple choice answer then that’s it

Answer:
x = -3
Explanation:
8(6x + 4) = -112
Divide both sides by 8.
6x + 4 = -14
Subtract 4 from both sides.
6x = -18
Divide both sides by 6.
x = -3
