Answer:  \\The\: width\: is \: 6 \:  {in}^{2}  \\ \\  Step\: by\: step\: explanation: \\ Let \:  x  \: be \:  the  \: width  \: of  \: the \:  rectangle,\: x > 0\Rightarrow the \: length:2x + 8 \\ We  \: have  \: an \:  equation:x(2x + 8) = 120 \\ \Leftrightarrow 2 {x}^{2}  + 8x  + 8= 128 \\ \Leftrightarrow  {x}^{2}  + 4x   + 4 = 64 \\ \Leftrightarrow {(x + 2)}^{2}  = 64 \\ \Leftrightarrow x + 2 =  \pm8 \\ \Leftrightarrow x = 6 \:  \vee \: x =  - 10 \\ \Rightarrow x = 6 \: (x > 0)

What is the area of a sheet of binder paper? (Binder paper is 8 1/2 inches by 11 inches.)
11Alexandr11 [23.1K]
Area of a rectangle is the product of length times width.  Thus, here we need the product of 8 1/2 inches by 11 inches.

One way of doing this follows:            8.5
                                                         8.5
                                                       ----------         
                                                         93.5 square inches

Rounding up, this comes out to 94 square inches.

Alternatively:     17             187
                         ---- * 11 = ------- = 93.5 square inches; rounded, that's 94.

Can someone please answer this question answer it correctly and show work please
mrs_skeptik [129]

Answer:

$1,216

Step-by-step explanation:

Costs for Handsome Homes fabric

Area (sq. ft.)   Cost (dollars)

        (x)                  (y)

       250               475

       500               950

       750               1,420

       1000             1,900

If you divide any y-value by its corresponding x-value, the quotient will be 1.9

This means that each square foot costs $1.90 at Handsome Homes

Discount Diggers = 20% per sq. ft. less than Handsome homes

Discount Diggers = $1.90 - 20%

Discount Diggers = $1.90(100 - 20%)

Discount Diggers = $1.90(0.8)

Discount Diggers = $1.52

Now that it is known how much 1 square foot of fabric costs at Discount Diggers, we need to find how much 800 square feet of fabric costs.

$1.52 = 1 sq. ft.

$1.52(800) = 800 sq. ft.

$1,216

800 square feet of landscape fabric at Discount Diggers costs $1,216

Hope this helps :)
