<span>h = –16t 2 + 64t + 8
since both the launch height and target height are identical we can say height is 0
solve for t
0 = -16t^2 + 64t +8
-8(2t^2-8t-1) =0
divide both sides by -8
2t^2-8t -1 = 0
t = 4.12 and -0.121
since it can't be a negative number:
t = 4.12 seconds ( round off as needed)

Hey there!!
Let's take the first number an the smallest number as ' x '
Then, the second consecutive even integer would become ' x + 2 '
Third integer ' x + 4 '
Hence, adding them up, we get,
x + x + 2 + x + 4
... 3x + 6
This is equal to 4 times the smallest number.
We got the smallest number as ' x '
Hence, the final equation :
... 3x + 6 = 4x
Hope my answer helps!!

There are a couple ways to determine the number of minutes it will take Charlie to run 9 laps, but the easist would be to find out what is happening to each number of laps in order to get the number of minutes. In each case, the number of laps is being multiplied by 5 to get the number of minutes.
9x5=45 minutes.
He is running each lap in 5 minutes.
