The length of rectangular pool is 6 ft and width of rectangular pool is 2 ft.

Step-by-step explanation:

Given,

Area of rectangular pool = 12 square feet

Let,

Width of pool = w

Length of pool = l = 2w+2

Area = Length * Width

12=(2w+2)*w\\12=2w^2+2w\\2w^2+2w-12=0

Dividing each term by 2;

\frac{2w^2}{2}+\frac{2w}{2}-\frac{12}{2}=0\\w^2+w-6=0\\w^2+3w-2w-6=0\\w(w+3)-2(w+3)=0\\(w+3)(w-2)=0\\

Either,

w+3 = 0       => w=-3

Or,

w-2=0          =>w=2

As width cannot be negative, therefore,

Width of rectangular pool = 2 ft

Length of rectangular pool = 2w+2 = 2(2)+2 = 4+2 = 6 ft

The length of rectangular pool is 6 ft and width of rectangular pool is 2 ft.

A football coach wants to see how many laps his players can run in 15 minutes. During a non-mandatory meeting, the coach asks fo
mestny [16]

Answer:

Step-by-step explanation:

There are three reasons here why randomization is not being applied.

First, the coach is only observing football players attending the meeting.  This is not representative of the entire team.

Second, there is no selection process.  The coach isn't using a random generator or using a similar method.

Third, the players are volunteering for the test.  The results will be biased because of this.

4(5x - 2) = 72<br> What do I do
Pepsi [2]

Answer:

x = 4

Step-by-step explanation:

4(5x - 2) = 72

Do the distributive property

20x - 8 = 72

Then add 8 to both sides to get 20x alone

20x - 8 = 72

      + 8  + 8

20x = 80

Then divide both sides by 20 to get x

\frac{20x}{20} = \frac{80}{20}

x = 4
