For question 6, the simplified expression is 3x + 19. You will get this by understanding that there are 3 groups of everything in the parentheses. You would read this expression as 4 and 3 groups of 5 and 3 groups of x (4+15+3x). Combine the 4 and 15 to get 19. Rewrite it so the part with the variable is first.
