Answer:
$13912.50
Step-by-step explanation:
First you find how much carpet you need by finding the area of the room.
18.75*28= 525ft^2
Then multiply the amount of carpet needed by 26.50 to find the total cost.
525*26.50= 13912.50
Hope this helps!

Look below.
Hopefully they're right.
Step-by-step explanation:
1. m=3/1 b=6
2. m=5/6 b=-5
3. m=-3/4 b=1
Let X be the width of the path.
The width of the path would be the width of the pool plus 2x, so 2x +16
The length of the path would be the length of the pool plus 2x, so 2x+22
The total area is 832 square feet.
Area is found by multiplying the length by the width.
So you have:
(2x+16) (2x+22) = 832
Use the Foil Method:
(2x+16) (2x+22) = 4x^2 +76x+352
Now you have:
4x^2 +76x+352 = 832
Subtract 832 from both sides:
4x^2 +76x+352-832 = 0
Simplify:
4x^2 +76x -480
Factor the left side:
4(x-5)(x+24) = 0
Divide both sides by 4:
(x-5)(x+24) = 0
Set both parenthesis to equal 0 and solve for x:
x=5 and x = -24
The width of the path cannot be a negative number, so the width is 5 meters.
We have that
x²<span> − 2x − 3 = 0
Step 1
</span>isolate the variable terms
<span>x² - 2x = 3
</span>Step 2
complete the square
<span>x² - 2x + 1² = 3 + 1² </span>
<span>(x-1)² = 4
</span>
the answer is the option (x-1)² = 4
