3 ft

8 ft

a.	P = (3 + x) + (8 + x)  

b.	P = 2(3 + x) + 2(8 + x) 

c.	P = 22 + 4x

d.	P = 3( 8 + x)

new garden

3 + x

8 + x

e.	P = 4(x + 5.5)

f.	P = 2(x+3)(x+8)

g.	P = 2(2x + 11)

		

PART B:  The garden below is 2 feet long and 8 feet wide.  The length and width of the original garden are going to be decreased by x feet.  Circle all of the expressions below that will be equivalent to the perimeter of the new garden. 

old garden

2 ft

a.	P = 10 – 2x + 10 – 2x 

b.	P = (2 – x) + (2 – x) + (8 – x) + (8 – x) 

8 ft

c.	P = 2(2 – x) + 2(8 – x)

d.	P = 20 + 4x

e.	P = 4(5 – x)

2 - x

new garden

f.	P = (8 – x) + (2 – x)

g.	P = 20 – 4x
