Answer:

S =19P\\S-19P = 0                              

Step-by-step explanation:

We are given the following in the question:

Let P be the number of professor and S be the student in a college.

According to the question:

There are 19 times as many students as professors.

We have to write an equation to show the given relationship between professors and students.

S =19P\\S-19P = 0

The above situation is the situation that represents the given relationship.

Consider the equation 5x (2x + 1) - 3(2x + 1) = 0.
kondor19780726 [428]

Answer:

It is equivalent to 15x – 3)(2x + 1) = 0.       False

It is equivalent to (5x – 3)(2x + 1) = 0        True

Either   x=-1/2   or    5/3

Step-by-step explanation:

Consider the equation 5x (2x + 1) - 3(2x + 1) = 0.

It is equivalent to 15x – 3)(2x + 1) = 0.       False

It is equivalent to (5x – 3)(2x + 1) = 0        True

When you take pull-out (2x+1), you will be left with (5x-3)

5x (2x + 1) - 3(2x + 1) = 0.

(2x+1)(5x-3)=0

Either 2x + 1 = 0                        

2x = -1    

Divide both-side of the equation by 2

2x/2 = -1/2                                    

  x= -1/2                                        

OR

5x-3 =0

5x = 3

Divide both-side of the equation by 5

5x/5 = 3/5

x = 5/3

Either   x=-1/2   or    5/3

Solve each equation by taking square roots<br><br> 2n^2 -8=-33
densk [106]
2n^2 -8=-33 

&#10;2n^2=-33+8&#10; &#10;    Add \ 8 \ to \ both \ sides 

2n^2=-25 

n^2=- \dfrac{25}{2}   Divide \ both \ sides \ by \ 2 

n=+ \sqrt{ -\dfrac{25}{2} }  <span> Take \ the \ square \ root \ of \ both \ sides  
</span>
n=+ \sqrt{ \dfrac{5i}{ \sqrt{2}}}
