rodikova [14]

Answer:

An undefined term is a term that can't be defined so easily. There really isn't a definition to define such terms. Consider the word "the." We use the word "the" all of the time, but do we really know how to define the word "the?" "Am" is another word that can't be defined so easily.

G/e^2-r=m-y please solve for e
allochka39001 [22]
Move r to the right side of the equation, G/e^2=m-y+r. Multiply both sides by e^2, G=(m-y+r)*e^2. Then divide both sides by m-y+r (it cannot be 0), G/(m-y+r)=e^2. Then e=+-\sqrt(G/(m-y+r)).
