The length of a rectangular garden is 2 feet more than twice it's width. If the area is 40 square feet, how much fencing would b
Westkost [7]

Answer:

w =4 ft and l =10 ft

Step-by-step explanation:

Let w = width

l = 2w+2

A = l*w

A = (2w+2)(w)

 40  = (2w+2) w

Distribute

40 = 2w^2 +2w

Subtract 40

0 = 2w^2 +2w - 40

Dividing each side by 2

0 = w^2 +w -20

Factor

0 = (w+5) (w-4)

Using the zero product property

w+5 =0     w-4=0

w= -5  w=4

Since we cant have a negative length

w=4

l = 2w+2 = 2(4)+2 = 8+2 =10

Paha777 [63]

Answer:

1. $60

2. 600 Calories were burned

3. D

Step-by-step explanation:

1. $75 x .20=$15

75-15=$60

2. What I started with is 200/40=5 calories burned per min

60 plus 60=120

5x120=600

3. It's the only option that has something decreasing. and there is a -5 which means it's getting subtracted or its decreasing.
