Which algebraic expression is equivalent to the expression below? 4 (5 + 8r) + 19

Answer:39+8r

Step-by-step explanation:

To find the answer you have to distribute the problem. To do this you do (4*5) and (4*8r). Whenever you do this you get 20+8r+19. You then need to add common factors in which for this problem would be 20 and 19. Whenever you add 20+19 you get 39 and then since the 8 has a r on the side you don't do anything with it so you just put 39+8r and that would be your answer

32r + 39

Step-by-step explanation:

Step 1: Distribute

4 (5 + 8r) + 19

20 + 32r + 19

Step 2: Combine like terms

32r + 39

Answer: 32r + 39
