Tina is planning to fence in an area for her dog. She wants to create a rectangular area of 1,600 square feet for her pet and ca
castortr0y [4]

The dimensions of the rectangular area of Tina's fence is 40 ft by 40 ft

<h3 />

<h3>Area of a rectangle:</h3>
  • area = lw

where

l = length

w = width

She wants to create a rectangular area of 1,600 square feet for her pet . Therefore,

  • area = 1600 ft²

lw = 1600

Therefore,

perimeter = 160 ft

Then,

perimeter of rectangle = 2(l + w)

160 = 2(l + w)

l + w = 80

Let's combine the equations

lw = 1600

l + w = 80

l = 80 - w

Therefore,

w(80 - w) = 1600

80w - w² = 1600

Therefore,

w² - 80w + 1600 = 0

w² - 40w - 40w + 1600 = 0

w(w - 40) - 40(w - 40) = 0

(w - 40)(w - 40) = 0

w = 40 or 40

Therefore, the dimensions can be calculated as follows:

lw = 1600

40l = 1600

l = 1600 / 40

l = 40 ft

Therefore, the dimensions are 40ft by 40 ft

Please help: 3(x+2)+2(x-4)=x-3(x+3)
qwelly [4]

<em>*Distribute*</em>

3x+6+2x-8=x-3x-9

<em>*Combine like terms*</em>

5x-2=-2x-9

<em>*Add 2x to both sides*</em>

7x-2=-9

<em>*Add 2 to both sides*</em>

7x=-7

<em>*Divide both sides by 7*</em>

x=-1

Hope this helps!!

victor has the map scale missing.he knows the distance from the lake to the youth center is 8 miles. on the map they are 2in. ap
kupik [55]
The <u>correct scale</u> is 1 in = 4 mi.

<u>Explanation</u>:

The scale tells us what a given measurement on the map equals in real-life distance.  

The measurement on the map that we have is 2 inches, and it equals 8 miles:

2 in = 8 mi

This can also be written as 2/8.  This fraction can be simplified, since both 2 and 8 are divisible by 2; it will simplify to 1/4.  This is the same as 
1 in = 4 mi.
