Hello!


\rm{4x^2\:for\:x=3}


  • \bf{Plug\:in\:-3\:for\:x.}


\hookrightarrow\rm{4(-3)^2}


  • \bf{Evaluate.\;Square\;-3\;first.}


\hookrightarrow\rm{4(9)}


  • \bf{Multiply.}


\hookrightarrow\rm{36}

Therefore, the answer is
\boxed{\boxed{\bf{36}}}.

Hope it helps!

Enjoy your day!


\boxed{\rm{Cordelia}}
