Simply multiply 0.7 by 100. 0.7 x 100= 70%. The answer is 70%
        
                    
             
        
        
        
Answer:
A = 5x³ + 17x² - 35x - 30
Step-by-step explanation:
the shaded area (A) is calculated as
A = outer area - inner area
    = (5x + 3)(x² + 4x - 10) - 3x(2x - 1) ← distribute parenthesis
    = 5x³ + 20x² - 50x + 3x² + 12x - 30 - (6x² - 3x)
   = 5x³ + 23x² - 38x - 30 - 6x² + 3x ← collect like terms
   = 5x³ + 17x² - 35x - 30
 
        
                    
             
        
        
        
We have 1 m = 100cm
          ⇒ 72 m = 7200 cm 
          ⇒ 7200 / 1.5= 4800 cm = 48 m
        
                    
             
        
        
        
Answer:
symmetric matrix is the square matrix and it is equal to its transpose
Step-by-step explanation:
solution
a symmetric matrix is the square matrix and it is equal to its transpose
As A is symmetric matrix  then 
A = 
here only square matrices will be symmetric
and matrix A is symmetric its mean its matrices have equal dimension
and every square diagonal matrix is also symmetric when all off diagonals element is zero 
symmetric matrix for all indices i and j
A = aij = aji
