Answer:
Axis of symmetry is 
C) x = 1
Step-by-step explanation:
we are given equation as

we can use axis of symmetry formula
Let's assume we are given quadratic equation as

Axis of symmetry is 

now, we can compare both equations 
and we get 

now, we can find axis of symmetry



 
        
                    
             
        
        
        
Answer:
Length and the width of the rectangle is 15.5 inches and 8.5 inches respectively.
Step-by-step explanation:
Given:
Length = 7 inches + Width
=> P = 48 inches
=> L = (7 + W) inches............. (1)
Perimeter 'P' is the sum of all sides of the rectangle 2 (L + W)
∴ 48 inches = 2 (L + W) .................(2)
Substitute for L in equation (2)
∴ 48 inches = 2 [(7 + W) + W]
48 = 2[7 + 2W]
48 = 14 +4W
48 - 14 = 4W
34 = 4W
W = 8.5 inches
Recall that: Length, L = (7 + W)
∴ L = (7 + 8.5)
L = 15.5 inches

Answer:
I win 10% = 217.8
I lost 10% = 178.2
217.8 + 178.2 = 396
198 + 198 = 396
396 = 396
I neither gain nor lose anything: V
