I working out some prealgebra solutions and I'm having issues. I've done the first 4 but I'm not confident with my answers.

Please remember to show ALL of your work on every problem. Read the basic rules for showing work below BEFORE you start working on the quiz. 1) Simplify each expression. First use the Distributive Property to clear parentheses and then combine like terms. a) 4 ( 5 x 2 ) + 3 x 20 x + 8 + 3 x (− 20 x + 3 x )+ 8 17 x + 8 b) 5 ( 6 3 y ) 8 y 30 15 y 8 y 30 +(− 15 y 8 y ) 30 23 y c) 6 a + 7 ( a 5 ) 6 a + 7 a 35 13 a 35 d) 4z + 3 ( z 1 ) ¿ 5 4 z + 3 z 3 5 7 z 3 5 7 z 8 e) 7 ( 3 w + 2 )−( 6 w 3 )
21 w + 14 6 w + 3 ( 21 w 6 w ) + 14 + 3 15 w + 14 + 3 15 w + 17 2) Perform the indicated operations, showing all work: 3 4 1 9 + ( 1 2 ) 2 3 4 1 9 +( 1 2 + 1 2 ) 3 4 1 9 + 1 4 3 36 + 1 4 1 12 + 1 4 = 1 12 + 3 12 1 12 + 3 12 = 2 12 2 12 = 1 6
