The answer is 3, if it is in square meters it must be a square therefore each side is the same length

1/(x+1) - 1/(x+2) = 1/2

Please include the instructions; I assume your job is to find the value of x.

<span>1/(x+1) - 1/(x+2) = 1/2 would better be written as
   
     1            1            1
</span><span>-------- - ------------ = ----
  x+1           x+2        2

Identify the LCD.  It is (x+1)(x+2)(2).  Mult. all 3 terms of the equation by this LCD:

2(x+2) - 2(x+1) = 2(x+1)(x+2)

We can factor out the 2 from all terms:

x+2 - x - 1 = x^2 + 3x + 2

Let's move all terms from the left to the right side:

 0              = x^2 + 3x + 2 - x - 2 + x + 1

Then x^2 + 3x + 1 = 0.  This is a quadratic with a=1, b=3 and c=1.

What is x?

       -3 plus or minus sqrt( 9-4(1)(1) )        -3 plus or minus sqrt(5)
x = --------------------------------------------- = ---------------------------------
                             2                                                    2

I rather expected to obtain an integer value for x.


Why don't you give this problem a try yourself?  Suggestion:  First mult. every term by 2.  This will give you:

   2          2
------- - ------- = 1   and this may be slightly easier to work with.  Please
 x+1      x+2          give it a try:  try to find x that satisfies this equation. 
                              Important:  note that x cannot equal either -1 or -2.

10. Write an inequality relating the measure of angle 1 to the measure of angle 2
patriot [66]
The two triangles are isosceles.

Both triangles have the equals sides equal to 6

Both ∠ 1 and the ∠2 are the opposite angles to the different side of their respective triangles.

The opposite side to ∠ 1 is shorter than the opposite side to ∠ 2, which implies that ∠1 is less than ∠2.

Then the inequality that relates those angles is

 ∠1 < ∠2

A party rental company has chairs and tables for rent. The total cost to rent
Tema [17]
2c+5t=43

c=(43-5t)/2

8c+3t=36 and using c found above in this equation gives you:

4(43-5t)+3t=36

172-20t+3t=36

-17t=-136

t=8, and since c=(43-5t)/2

c=1.5

So a table costs $8.00 to rent and a chair costs $1.50
