ANSWER

The simplified expression is

[tex]2x + 28[/tex]




EXPLANATION


The given expression is,

[tex]2(10) + 2(x - - 4)[/tex]

Let us deal with the bracket first.

The two negatives in the parenthesis will become positive.



The expression now becomes,


[tex]2(10) + 2(x + 4)[/tex]


We now expand the parenthesis to get,


[tex]20 + 2x + 8[/tex]


We group like terms to obtain,



[tex]2x + 8 + 20[/tex]

This simplifies to,


[tex]2x + 28[/tex]
