Answer:
    x = 4
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 
                     -5*x+15-(35-10*x)=0 
 Pull out like factors :
              5x - 20  =   5 • (x - 4) 
_________________________________________
 Solve :    5   =  0
This equation has no solution.
A a non-zero constant never equals zero.
_________________________________________
Solve  :    x-4 = 0 
 Add  4  to both sides of the equation : 
                      x = 4 
 
        
                    
             
        
        
        
Answer:
x³ - 10x² + 31x - 30
Step-by-step explanation:
Given
(x - 2)(x - 3)(x - 5) ← expand the second pair of factors using FOIL
= (x - 2)(x² - 8x + 15) ← distribute
= x³ - 8x² + 15x - 2x² + 16x - 30 ← collect like terms
= x³ - 10x² + 31x - 30

Prime factorization of 48 is :

Option (3) is true.
9. 
Prime factorization of 19 is:
19 = 19 × 1
Option (c) is correct.
(10).
Prime factorization of 924 is:
924 = 2 x 2 x 3 x 7 x 11
= 2² x 3¹ x 7¹ x 11¹
Hence, this is the required solution.
 
        
             
        
        
        
The perimeter of the parallelogram is 14x + 8. You add 3x+9+4x-5+3x+9+4x-5 to get the answer.
