5 0

Answer:

Step-by-step explanation:

1. 12

2. 12/3.5 = 3.43

3. 12/15 = 0.8

4. 3.43/0.8

5. 315/x

6. 315/x = 0.8/3.43

7. (315)(3.43) = 0.8x divide both sides by 0.8, so x = 1,350.5625 feet.

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
