Answerthe simplified expression is
![2x + 28](/tex.php?f=2x + 28)
explanationthe given expression is,
![2(10) + 2(x - - 4)](/tex.php?f=2(10) + 2(x - - 4))
let us deal with the bracket first.the two negatives in the parenthesis will become positive.the expression now becomes,
![2(10) + 2(x + 4)](/tex.php?f=2(10) + 2(x + 4))
we now expand the parenthesis to get,
![20 + 2x + 8](/tex.php?f=20 + 2x + 8)
we group like terms to obtain,
![2x + 8 + 20](/tex.php?f=2x + 8 + 20)
this simplifies to,
![2x + 28](/tex.php?f=2x + 28)
