Answer:
A) But if anyone thinks this they should go back to preschool
Step-by-step explanation:
On any other value of x you would take the numerators and denominators and multiply them across:

But, this literally does not make since considering the fact that you cannot divide any value by zero. Try it, it won't work. If we plug these into a trusty dusty calculator, we get this:

0*DOMAINERROR= You can't do it.
There are other reasons why you can't divide by zero, I would suggest looking them up on YT and learning about them.
I would answer A, but the person who wrote this question just wasn't focusing when they wrote the question.
 
        
             
        
        
        
1. Yes , Yes
2. Yes , Yes
3. No , No
4. No, Yes
        
             
        
        
        
The answer would be (x+1)(x+3)
        
                    
             
        
        
        
Sin 30= x/8
X= sin 30*8
X=4
        
             
        
        
        
Answer:
Width is 10  Length is 20
Step-by-step explanation:
Perimeter = 60
Length = W + 10
P = 2L + 2W                      Write the equation for perimeter
60 = 2(W + 10) + 2W         Substitute your variables
60 = 4W + 20
- 20          - 20                Subtract 20 from both sides
40 = 4W                        Divide both sides by 4
10 = W
