See a solution process below:

First, evaluate the expression within the parenthesis:

#4[9 - (color(red)(5) - color(red)(7))] =>#

#4[9 - (-2)] =>#

#4[9 + 2]#

Next, evaluate the expression within the brackets:

#4[color(red)(9) + color(red)(2)] =>#

#4 * 11#

Now, evaluate the remaining multiplication expression:

#4 * 11 => 44#
