To find the factor a a polynomial from its roots, we are going to seat each one of the roots equal to

, and then we are going to factor backwards.
We know for our problem that one of the roots of our polynomial is -3, so lets set -3 equal to

 and factor backwards:



 is a factor of our polynomial.
We also know that another root of our polynomial is 

, so lets set 

 equal to 

 and factor backwards:




(

 is a factor of our polynomial.
We can conclude that there is no correct answer in your given choices.
 
        
        
        
Answer:
   x = 31
Step-by-step explanation:
The perimeter is the sum of the equal-length sides:
   63 = (x -10) +(x -10) +(x -10)
   63 = 3x -30 . . . . . . . . collect terms
   21 = x -10 . . . . . . . . . . divide by 3
   31 = x . . . . . . . . . . . . . add 10
 
        
             
        
        
        
I am guessing you have to rotate it 180 degrees and see if it fits in the area in which it’s supposed to fit it’s there another part to the question?
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Equation is t÷5=8
first you multiply 5 on each to cancel it out
t÷5*5=8*5
solve to get 
t=40
 
        
             
        
        
        
Answer:
$1.80
Step-by-step explanation:
2/3x = 1.2
x = 1.2 / (2/3)
x = 1.2 * (3/2)
x = 1.80
