Answer:

\frac{2(x - 4)}{(x - 2)(x + 2)}

Step-by-step explanation:

\frac{2}{(x - 2)}  -   \frac{8}{ ({x}^{2} - 4 )}  \\  \frac{2}{(x - 2)}  -  \frac{8}{(x - 2)(x + 2)}  \\  \frac{2(x + 2) - 8}{(x - 2)(x + 2)}  \\  \frac{2x + 4 - 8}{(x - 2)(x + 2)}  \\  \frac{2x - 8}{(x - 2)(x + 2)}  \\  \frac{2(x - 4)}{(x - 2)(x + 2)}

The difference between two integers is 32.The ratio of these integers is 1:3.Find these integers​
shutvik [7]

Answer:

16 and 48

Step-by-step explanation:

let the 2 integers be x and 3x ← ratio 1 : 3

Then

3x - x = 32 ← difference between the integers

2x = 32 ( divide both sides by  2 )

x =  16

and 3x = 3 ×  16 =  48

Since magnitude of difference is 32

We can also express the difference as

x - 3x = 32

- 2x = 32 ( divide both sides by - 2 )

x = - 16

and 3x = 3 × - 16 = - 48

The 2 integers are 16 and 48 or - 16 and - 48

1. sqrt 52 = 7.211 rounds to 7

2. irrational number

3. sqrt 441 = 21....rational

4. 12^2 + 3^2 = h^2
    144 + 9 = h^2
     153 = h^2
      sqrt 153 = h
      12.4 = h <===

5. 6^2 + b^2 = 18^2
    36 + b^2 = 324
    b^2 = 324 - 36
    b^2 = 288
    b = sqrt 288
    b = 16.97 rounds to 17 <==

6. 39^2 + 52^2 = c^2
    1521 + 2704 = c^2
    4225 = c^2
    sqrt 4225 = c
    65 = c
    (39 + 52) - 65 = 91 - 65 = 26 miles shorter <==

7. 4^2 + b^2 = 16^2
     16 + b^2 = 256
     b^2 = 256 - 16
     b^2 = 240
     b = sqrt 240
     b = 15.49 rounds to 15.5 <==

Step-by-step explanation:

Y=4x+4

Y-4=4x

X=(Y-4)/4

Y=number of U.S. households, in millions.

Y≥40

Y-4≥36

(Y-4)/4≥9

So, X≥9.
