here's some help on the practice problems
41.) 3(b+2)+2b
Distribute the three into the parenthesis. 3b+6+2b
Combine like Terms which are 3b and 2b 3b+2b+6= 5b+6
Simplified Answer 5b+6
42.) 5(x+3)-8x
distribute the 5 into the parenthesis. 5x+15-8x
Combine like terms which are 5x and -8x 5x-8x+15=-3x+15
Simplified Answers -3x+15
43.) -3(a+2)-a
Distribute the 3 into the parenthesis -3a-6-a
Combine like terms which are -3a and -a -3a-a-6= -4a-6
Simplified Answer -4a-6
44.) -2(x+3)-a
Distribute the -2 into the parenthesis -2x-6+2x
Combine like terms which are -2x and 2x since -2x+2x-6= -6
those are the same number but one is
negative and the other one is positive
they both cancel out.
Simplified Answer 6
46.) 8a-2(a-7)
Distribute the -2 into the parenthesis 8a-2a-14
Combine like terms which are 8a and -2a 8a-2a-14=6a-14
Simplified Answer 6a-14
Distribute the three into the parenthesis. 3b+6+2b
Combine like Terms which are 3b and 2b 3b+2b+6= 5b+6
Simplified Answer 5b+6
