Answer:
x = - 3 ± 3
Step-by-step explanation:
given the equation x² + 6x - 9 = 0
We can solve for x using the quadratic formula
x = ( - b ±  ) / 2a
 ) / 2a
with a = 1, b = 6 and c = - 9
x = ( - 6 ±  ) / 2
 ) / 2
   = ( - 6 ±  ) / 2
 ) / 2
   = ( - 6 ±  ) / 2
 ) / 2
   = ( - 6 ± 6 ) / 2
 ) / 2
x = - 3 ± 3
 
        
             
        
        
        
I think is
9 + x = 16 + 27
9 + x = 43
x = 52
        
             
        
        
        
Answer: A
Step-by-step explanation:
Your answer is A.
Value of 3.78 x 10=37.8
Value of 5.99 x 102=699.98
value of 7.35 x 10-12=61.5
Value of 9.46 x 10-10=84.6.
Least value to greatest value
3.78 x 10=37.8 Least value
7.35 x 10 - 12=61.5 Sencond least value
9.46 x 10 - 10=84.6  Sencond greatest value
5.99 x 102=699.98  Greatest value
Hope it helps have a great day:)
 
        
             
        
        
        
Is there a picture for this
        
             
        
        
        
2l + 2w = 132
l = 3w + 2
2(3w+2)+2w=132
6w + 4 + 2w = 132
8w + 4 = 132
8w = 128
w = 16
l = 3(16) + 2
l = 48 + 2
l = 50
2(50) + 2(16) __ 132
100 + 32 = 132
