Step-by-step explanation:

Figure C
Appears to be an equilateral triangle.
<h3>
Answer:</h3>
The first line.
<h3>
Step-by-step explanation:</h3>
If we let x represent "a number", then "a number divided by 3" is x/3. The denominator is missing on the first line.
Further, this "is 4 more than -11", so is = 4 + (-11). The constant 4 is on the wrong side of the equal sign in line 1.
_____
The solution should be ...
... x/3 = 4 + (-11)
... x = 3·(-7)
... x = -21
___
<u><em>Check</em></u>
-21 divided by 3 is -7. That is 4 more than -11.
Answer:
2.58 seconds
Step-by-step explanation:
When you complete the square, you get ...
h = -16(t -9/16)^2 +60 +81/16
Then the solution for h=0 is ...
t = (x -9/16)^2 = 1041/256
t = (9 +√1041)/16 ≈ 2.57903 ≈ 2.58
It takes about 2.58 seconds for the ball to hit the ground.
