Answer :
The given expression is:
[tex]-12(6-8)^2\div(-3)+3\cdot4[/tex]We need to solve first the parentheses, so:
[tex]\begin{gathered} -12(-2)^2\div(-3)+3\cdot4 \\ \\ =-12(4)\div(-3)+3\cdot4 \end{gathered}[/tex]Now, solve the multiplications:
[tex]=(-48)\div(-3)+12[/tex]The next operation to solve is the division:
[tex]=16+12[/tex]Finally, solve the addition:
[tex]=28[/tex]The answer is 28
