if a b 9 are in GP
b÷a = 9 ÷ b
b^2 = 9a 
if a - 1 b 9 are in AP 
2b = a+8
b = a+8÷2 
substitute 
 b is equal to a + 8 by 2 in b square equal to 9 a
(a+8÷2)^2 = 9a
a^2+16a+64 = 36a
a^2 -20a +64 =0
(a-16) (a-4) =0
a= 16 or a=4
when a=16 b= 12
when a=4 b= 6
Value of a and b are given above 
 
        
             
        
        
        
Answer:
28.125

450 divide by 16 = 28.125
 
        
             
        
        
        
Answer:
2 inches
Step-by-step explanation:
a=Lw
v=lwh
lw= 7
14/7=2
 
        
             
        
        
        
If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.
Your answer is A.
