X / 6 + 2 = 9
x/6 = 9 - 2
x/6 = 7
x = 7 * 6
x = 42 <== ur number

Answer:
The instantaneous velocity after eight seconds is 9 m/s
Step-by-step explanation:
Given as :
The ball shot upward with velocity of 15 m/s
The height of the ball after t sec is given as h(t) =  
 
Now, The instantaneous velocity after 8 sec = 
Or, The instantaneous velocity =  
 
or, The instantaneous velocity = 
Now at t = 8 sec
The instantaneous velocity = 5 + 4 = 9 m/s
Hence The instantaneous velocity of ball at t = 8 sec , is 9 m/s  Answer 
 
        
             
        
        
        
Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:

Where,  are parallel sides and
 are parallel sides and  is the vertical distance between the parallel sides.
 is the vertical distance between the parallel sides.
Putting  in the above formula, we get
 in the above formula, we get




Therefore, the area of the trapezium is 408 square cm.
 
        
             
        
        
        
That’s not enough information to say how long he could do it. He could go slower or faster than her but by how much if so. So it’s not enough info.
