lisa evaluated the expressions 2x and x^2 for x=2 and found that both epressions were equal to 4. lisa concluded that 2x and x^2 are equivalent expressions. How could you show lisa that she is incorrect?

because X squared isn't the same as 2 multiplied by X(any variable) meaning the moment you change your variable the expressions wouldn't equivalent.

EX.) 2*420=840 and 420^2=176400

Answer:

Choose another number.

Step-by-step explanation

We could take x=3 and evaluate, for the first expression we would have

\(2x=2\cdot3=6\)

and for the secod expression we would have

\(x^2=3^2=9\)

For this choosen x, we would have

\(2x=6 eq9=x^2\)

which would show lisa that she is incorrect.
