Lebron james wants to construct a privacy fence around his 23 million dollar home in la. fencing will cost him $48 per yard. the length is 250 less than 4 times the width. the fence will cost him $24,000. find the length and width of his property.

Hi there!

Important information we know:

Fencing costs $48 per yard (1 yard = $48)

Width : X

Length : 4X - 250

Total cost of fencing : $24,000

Steps to finding the

1. First off, you'll need to find how many yards the fencing is (the perimeter of the fencing). To do so, You need to use the cross product method with the information you know about the cost of the fencing per yard and the total cost of the fencing :

1 yard fencing = $48

? yards fencing = $24,000

(1 × 24,000) ÷ 48 = ? yards fencing

24,000 ÷ 48 = ? yards fencing

500 = ? yards fencing

This means that the perimeter of the fencing is 500 yards.

2. Now that you have the perimeter of the fencing, you'll need to use the general formula of the perimeter of a rectangle and replace all the information you have in it (I'm guessing that the fencing is in a rectangular shape because it's the most common shape and that the information is not mentionned) :

P = (Length × 2) + (Width × 2)

P = 500

Length = 4X - 250

Width = X

500 = ((4X - 250) × 2) + (X × 2)

3. Now that you have your equation, all you need to do next is to solve it by isolating "x" to find the width :

500 = ((4X - 250) × 2) + (X × 2)

(4X - 250) × 2 = (4X × 2) + (-250 × 2)

4X × 2 = 8X

-250 × 2 = -500

(4X - 250) × 2 = 8X - 500

(X × 2) = 2X

500 = 8X - 500 + 2X

Add 500 to each side of the equation → 500 + 500 = 1,000

1,000 = 8X + 2X

Add similar terms together → 8X + 2X = 10X

1,000 = 10X

Divide each side of the equation by 10 → 1,000 ÷ 10 = 100

100 = X → The width of his fencing is 100 yards.

4. Now that you know the width of the fencing, you just need to replace the "X" in the length in order to find its measure :

Length = 4X - 250

Length = 4(100) - 250

Length = 400 - 250

Length = 150 → The length of his fencing is 150 yards.

There you go! I really hope this helped, if there's anything just let me know! :)

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
