Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
 3x² = 147
 x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
 √a = a¹/² so (x²)¹/², and (x²)¹/² = 
x²×¹/² = x, therefore the solution is
x = +/- 7.
 
        
             
        
        
        
Answer: 11.25 secs
Step-by-step explanation:
So in this sense the rockets origin or the ground is modeled at h=0 so the time required if used on a table shows that h=0 between the values of 11 and 12. So if you plug and chug decimal values between these two values you get exactly 0 at t=11.25 so it takes approximately 11.25 seconds for the rocket to return to the ground
