well, 26+6 is 32, so divide that by 3 and you'd get 10.67, making daniel 32 by that time and his son being 10 years old
its simple math really, also, i hope this helps you ^-^
 
        
                    
             
        
        
        
Volume of a cube is expressed using 
V= a^3 
I can’t really see what the volume says in the picture, if the number there says 3
x wouldn’t be 3 because the volume is already given 
It would be 
a^3= 3 
a= 3√3
        
             
        
        
        
Inverse of the function 2x-6y=1
To get the inverse of the function, first, interchanged
the variables such x will be y and y will be x.
<span>(1)   </span><span>       2y – 6x = 1</span>
Then, find the value of y in the new equation,
<span>(2)   </span><span>      2y – 6x + 6x = 1 + 6x</span>
2y
= 1 + 6x
<span>(3)   </span>(1/2)(2y)
= (1 + 6x)(1/2)
<span>            y = (1 + 6x) / 2</span>
<span>The reverse of the function
is y
= (1 + 6x)/2.</span>
 
        
             
        
        
        
Idk if this is what you're looking for at all but the 9th number in that sequence would be 54
