Answer:
<em>3.94 seconds </em>
Step-by-step explanation:
h = - 16t² + 248
If stone is dropped, then h = 0
- 16t² + 248 = 0
t² =
t = ±
t < 0 is a solution of equation, but not a solution of the task
t = ≈ <em>3.94 seconds</em>

Step-by-step explanation:
Let's solve your equation step-by-step.
4x+2=2x+12
Step 1: Subtract 2x from both sides.
4x+2−2x=2x+12−2x
2x+2=12
Step 2: Subtract 2 from both sides.
2x+2−2=12−2
2x=10
Step 3: Divide both sides by 2.
2x
2
=
10
