    Answer:option A is the correct answer

    Step-by-step explanation:

    The given expression is

    4 (x + 5) + 4x + 8

    To simplify the given expression, the first step is to open the parenthesis by multiplying each term in the parenthesis by the term outside of the parenthesis. It becomes

    4x + 20 + 4x + 8

    Next step is to add like terms. We would do this by adding each term containing x together and also add the constants together. It becomes

    4x + 4x = 20 + 8

    8x + 28

    Since 4 is a common factor of both terms, we would factorize 4 out. It becomes

    4 (2x + 7)
