see a solution step below;

Explanation:

#2c(a + b)#

Where;

#a = 12#

#b = 9#

#c = 4#

All we need to do is to replace the values into the equation, for example since #a = 12# it means that, whereever there is #a# we should replace it with #12#, same goes for another values..

#2c(a + b)#

#2(4)[(12 + 9)]#

Remember PEMDAS

We have to simplify the Parasynthesis first before anything else..

Hence;

#2(4)[(12 + 9)]#

#2(4)[21]#

#8[21]#

#168#
