4 (x + 5) + 4x + 8 which of the following is equivalent to the expression above.

a) 4 (2x + 7)

b) 8 (x + 4)

c) 5x + 17

d) 8x + 13

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)
