X = 7, -3, 2
(x - 7)(x + 3)(x - 2) = 0
(x - 7)(x^2 + x - 6) = 0
x^3 - 6x^2 - 13x + 42 = 0

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one.
azamat
To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above:

 -  The<span> room has square dimensions and it has been built with two pieces of sheetrock, a smaller one and a larger one.

 2. Therefore, let's call

 x: the smaller one.
 y: the larger one.

 3. Then, you have that the lenght of the wall is the sum of the smaller one and the larger one:

 x+y

 4. So, the area of the room is:

 (x+y)(x+y)
 (x+y)</span>²

 Therefore, the answer is: (x+y)²

A kite, flying 50 feet high in the air is attached by a string to a stake in the sand. How long is the string to the nearest ten
Vlad [161]
Height of the kite from the ground = 50 feet
Angle at which the kite is flying = 45 degrees
Let us assume the length of the string = x feet
Then
x = 50 * (square root 2)
   = 50 * 1.414
   = 70.7 feet
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or option "b".

all we have to do is divide 3392 by 32 
so lets do the math:)
3392 ÷ 32 = 106 
so the length is 106!
hope this helps:)
