We are given the following expression:
[tex]\mleft(-3\mright)\mleft(-5+\mleft(-8\mright)\mright)=n[/tex]First, we will solve the expressions inside the parenthesis:
[tex](-3)(-5-8)=n[/tex]Now we have two terms that have the same sign, therefore, we add them together and the result will have that sign, that is:
[tex](-3)(-13)=n[/tex]Now we have the product of two negative number, therefore, we multiply them together and the result will have a positive sign:
[tex]39=n[/tex]Therefore, n = 39.
