The scientist benjamin thompson observed that heat was generated when a moving drill contacted a piece of metal. how can thompson’s observation be explained by the kinetic theory of matter

the correct answer would be 6 feet.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

this is math not biology xd
