HW- Wednesday October 15 - SEVENTH Grade

Complete the following in your journal.  We will check these in class tomorrow.


Simplify the following expressions.  Remember to combine "like terms" and use any shortcuts to cancel out inverse terms.

1.)   x + x + x + 10 + 12 + x + x

2.)  3x +  18  + x - 12  -x + 6

3.)  x + x + x + 24 - 3x - 10 - 14

4.)  a +  b  +  10  +  2b  -a  - 4

5.)  3a  +  2b  -5  +  3b  - a  + 11

For the following, find the greatest common factor and factor out.  Use the distributive property to help you check it and use your notes for help.

6.)    3x +  15  =   __ ( ___ + ___  )            7.)  4x + 24 =   __ ( ___ + ___  )

8.)   10x + 25=   __ ( ___ + ___  )              9.)   18x +  30=  __(___ + ___) 

Simplify the expressions.  Then factor it out.

10.    4 + 3x  +  20  +  x +  x - 4  -2x +1

simplified:                                     factored:   ___( ___ +  ___)
