Determine the width of the garden. nina must put 60 feet of fencing around her rectangular garden. the length of the garden is three feet longer than twice the width. what is the solution set for 2w + 2(2w + 3) = 60 given the replacement set {6, 7, 8, 9}?

2w+2(2w+3)=60

2w+4w+6=60

6w+6=60

6w=54

w=54/6 =9

 the width is 9 feet

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
