Justify each step used to simplify the expression.
1. 3x+2y-2x+3=3x-2x+2y+2
2. =(3x-2x)+2y+2
3. =(3-2)x+2y+2
4. =x+2y+2

See below.

Step-by-step explanation:

To simplify the expression use properties of algebra to combine like terms:

1. Expression                          3x-2x+2y+2            

2. Associative Property         (3x-2x)+2y+2

3.  GCF                                    (3-2)x+2y+2

4.  Subtraction                         x+2y+2

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
