We need to find the sum of
" the product of the coefficient 8 and the variable k"
and
" product of the factors '12' and '16'.
The first line can be written as >>>>
[tex]8k[/tex]The second line can be written as >>>>>
[tex]\begin{gathered} 12\times16 \\ =192 \end{gathered}[/tex]The sum of both of these expression can be written with a '+' in between. That is
[tex]8k+192[/tex]
