We can simplify this equation and find the value of k.

k ÷ 2 + 1 - 1k = -2k
k ÷ 2 + 1 = -k
k + 1 = -2k
1 = -3k
k = -1/3

Answer:   k = "- \frac{2}{3}"  ; or, write as:   " -0.667 " .

_________________________________________________________
Given:

(k/2)  + 1  -  1k  = -2k ;  
_________________________________________________________

Add "1k" to each side of the equation:

(k/2)  + 1  -  1k  + 1k  =  -2k + 1k  ;

to get:


(k/2)  + 1  =  -1k ; 

Multiply the ENTIRE EQUATION (both sides) by "2" ;  
               to eliminate the "fraction" ;

2 * [ (k/2) + 1 = -1k ] ;


to get:

k + 2 =  -2k  ;

Subtract "k" from each side of the equation;

k + 2 - k = -2k - k ;

to get:

2  =  -3k ;

↔  

-3k = 2 ;

Divide each side of the equation by "-3" ; to isolate "k" on one side of the equation ; &  to solve for "k" ;

-3k / 3  = 2/-3 ;

to get:

k = - \frac{2}{3}  ; or, write as:   " -0.667 "

The square shown has a perimeter of 32 units. The square is rotated about line k. What shape is created by the rotation and what
harkovskaia [24]
The perimeter of the square is calculated through the equation,
                                        4x = P
where P is the perimeter and x is the measure of the sides.

When P is 32 units then,
                                         32 units = 4(x)
                                                 x = 8 inches

This 8 inches is the diameter of the cylinder formed by the rotation. 
The circumference of the base is calculated through,
                            C = 2πr = πD
Substituting the known values,
                              C = π(8 units) = <em>8π units
</em>
<em></em>When π is equal to 3.14, we solve for the numerical value of the cylinder as follows,
<em>                                      C = 8(3.14) = 25.12 units
</em>
<em></em>Thus, the figure formed is a cylinder with base circumference equal to 25 units. The answer is the third choice. <em>

Solve the equation 6w2 – 7w – 20 = 0.
azamat

For this case we have the following quadratic equation:

6w ^ 2-7w-20 = 0

Where:

a = 6\\b = -7\\c = -20

Its roots will be given by:

w = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}\\w = \frac {- (- 7) \pm \sqrt {(- 7) ^ 2-4 (6) (- 20)}} {2 (6)}\\w = \frac {7 \pm \sqrt {49 + 480}} {12}\\w = \frac {7 \pm \sqrt {529}} {12}\\w = \frac {7 \pm23} {12}

The roots are:

w_ {1} = \frac {7 + 23} {12} = \frac {30} {12} = \frac {15} {6} = \frac {5} {2}\\w_ {2} = \frac {7-23} {12} = \frac {-16} {12} = - \frac {8} {6} = - \frac {4} {3}

Answer:

w_ {1} = \frac {5} {2}\\w_ {2} = - \frac {4} {3}

What is geometry? get follows if u follow me​
Shkiper50 [21]

Answer:

It really determines what geometry is.
In simple terms geometry is just shapes.

That’s it really.

You have multiple theorems, postulates, and definitions to help you assist in proofs of theorems or jsut understanding of basic shapes.

If the answer is L * W * H then why do you have to divide once you get to H to get the correct answer?
Kisachek [45]

Answer:

Hi! I'm not quite sure what you entirely mean by this but I'll try to help. LxWxH is a formula used to find the volume of a rectangular prism or a box. If this is what you are using it for then there shouldn't a reason to divide. Unless maybe you're trying to find half of a box or you are trying to find the value of one of these in an equation but that's the only thing I can think of. Do you think you might be able to post an example in the comments?
