Answer:

<em>The dimensions of the area will be 8 ft x 40 ft</em>

Step-by-step explanation:

<u>Area and Perimeter</u>

The perimeter can be understood as the distance measured around a shape. The area gives us the idea of the space occupied by the shape. Being w and l the width and length of a rectangle, the perimeter and areas can be computed as follows

A=wl

P=2w+2l

The dog trainer has 96 ft of fencing to cover a 320 ft^2 rectangular area. This means that

wl=320

2w+2l=96

A system of equations is formed

\left\{\begin{matrix}wl=320\\ 2w+2l=96\end{matrix}\right

We divide the last equation by 2

w+l=48

solve for w

w=48-l

Replacing in the first equation

(48-l)l=320

Operating and arranging

l^2-48l+320=0

(l-8)(l-40)=0

We have two possible answers

l=8,\ l=40

Which gives us

w=40,\ w=8

In any case, the dimensions of the area will be 8 ft x 40 ft

Martinez purchased a pair of shoes on a web site. the original price of the shoes was $75. she used a coupon code to recive 20%
tankabanditka [31]

Answer:

$9 or 9% less

Step-by-step explanation:

Original Price = OP

$75= OP

75 x .2 (20% discount) = 15

$15 discount

$75 - $15 = $60

$60 x .1 (service fee) = 6

$60 + $6= $66

Op ($75) - $66 = 9

$9 less than OP

How I check the percentage (probaly not how ur supposed to but ah well)

75 = 100%

75 + 25 = 100 but 25 more than 100%

66 + 25 = 91, also makes 75 100% again

100%-91%=9%

dezoksy [38]

So basically when u square -5 or +5, u get 25 either way

And since the square root of x is greater than or equal to 25, u can use both of them for answers.
