Area is defined as L x W     L as shown in the picture  is   8x -10

W = 2x (wall) + 2x (pool) = 4x

so L * W =  (8x-10) (4x) =  32x^2 - 40x = Patio Area

Then substitue 9  for x   to get the second answer......  (32*81-40*9 = 2232 sq ft 

   2232 sqft x $10 /sqft = $22320

Do you have any idea on how to find all of them?

CPhill

That's not true, for example, take sqrt(2) and 1+sqrt(2), their difference will be rational. Maybe, from some point, pi and e have the same decimals, so the difference will be rational

n = 5,  m  = 11

n = 7, m =   71

I'm sure other integer soluitons are possible, as well.......!!!

Irrational......since both are irrational, there is no "common denominator" possible......so.....an irrational  results from their diffference.....

Rouded to whole number :  2

              to tenths                 2.2

                  hundredths         2.22

                   thousandths          2.222       I think you can see the pattern here..

as a fraction   20/9

So g(x)  =  -3/x^3  -x^2      (the 'x' s negate each other)

WHat do you want to do with this?

Times printing 8 as the units digit  =  10 (8)  + 2  = 82

Times printing 8 as the tens digit  = 10(8)   = 80

Times printing 8 as the hundreds digit  = 20

Total =  82 + 80 + 20  =  182 times

EP is correct.....we don't mind doing a few problems, but you will never learn if you don't try some yourself.....besides.....many of these are the same.....the numbers have just been changed to protect the innocent....

Everyone is smart if they try.....

Can you solve the rest @cphil? Your doing great!

Um, I have to finish by today.

Here is an idea tertre....instead of us doing your homework......why don't you try to solve the problems and post your attempts here and we will see how you are doing and help you along ???   Cool?

Yeah, take x on 1 side.

3. Suppose you wish to have $20,000 in your account at the end of six years.  The account pays annual interest of 3% compounded quarterly.  How much money will you need to invest in the account now?

20000 = A (1 + .03/4)^(6 * 4)   divide both sides by  (1 + .03/4)^(6 * 4)

20000 / (1 + .03/4)^(6 * 4)  = A  ≈  $ 16,716.63

5000(1.04)^5  -  5000 =  5000 [ (1.04)^5 - 1 ]  ≈  $1083.26

4^3 = 4*4*4 

=64

1 rotation = 360 degrees 

90 rotations = 90 x 360 =32400

1 min = 60 seconds

therefore  = 32400/60= 540 degrees/sec

therefore the answer = 540 degrees/sec

( x + 2) / (x^2 - 2x - 24 )  =

( x + 2)  / [ (x - 6) (x + 4 ) ]

The domain  is   ( - inf , - 4) ∪ ( - 4, 6) ∪ (6 ,inf)

Graph :

I agree with Melody, that it'll still be infinity.

Infinity is not a number, it's endless.

48 is to 40%  as 'x' is to 100% ?

48/40%  =  x/100%    Multiply both sides by 100%

120=x
