Answer:

width = 3.5 feet        length = 8 feet.

Step-by-step explanation:

 W=x

L=2x+1

Area=(2x+1)x=28

2x^2+x=28

2x^2+x-28=0

 (2x-7)(x+4)=0

x=3.5,-4.  It should be a positive number so W=3.5

2x+1=8          2x3.5=7     7+1 = 8    L=8

That area is 28 ft^2

width is 3.5 feet and length is 8 feet.

<u>Answer:</u>

<h2>SA = 157 in²</h2>

<u>Steps:</u>

SA = 2LW + 2WH + 2LH

SA = 2(9×2) + 2(2×11/2) + 2(9×11/2)

SA = 2×18 + 2×22/2 + 2×99/2

SA = 36 + 22 + 99

SA = 157 in²

6n-3&gt;-18 please show work
maxonik [38]
First off, add 3 to both sides of the equation.
6n - 3 + 3 > -18 + 3
Then, your equation should look like this: 6n > -15
Next, divide both sides by 6.
6n/6 > -15/6
Your answer is n > -5/2
