Answer:
if 4x square is the question the answer will be 144 or if 4x multiply by 2 then the answer will be 24
A nice physics problem.
But 16t 2 is inappropriately written; you meant x = 16t^2, where "^" represents exponentiation.
The appropriate formula applying to this situation includes a "t" term which is not present in yours. Start with this:
s = s_0 + v_0t + (1/2)a^t^2, where x_0 is the initial height above the ground and v_0 is the initial velocity. "a" represents acceleration an here is -32.2 ft/(sec^2).
Here's how we apply this formula:
0 ft = 64 ft + 0*t + (1/2)(-32.2 ft/(sec^2), or
0 ft = 64 ft - 16.1 ft/(sec^2)
You must solve this equation for time, t. It will be a positive quantity.

Find the coordinates of the point which divides the join of (-1,7) and (4,-3) in the ratio 2:3 ?
<h2><u>Solution</u>:-</h2>
Let the given points be A(-1,7) and B(4,-3)
Now,
Let the point be P(x, y) which divides AB in the ratio 2:3
Here,
<h3>
</h3>
Where,
= 2 , 
= 3
= -1 , 
= 4
Putting values we get,
x = 
x = 
x = 
x = 1
Now,
Finding y
<h3>
</h3>
Where,
= 2 , = 3
= 7 , = -3
Putting values we get,
y = 
y = 
y = 
y = 3
Hence x = 1, y = 3
So, the required point is P(x, y)
= P(1, 3)
<h3>The coordinates of the point is P(1, 3). [Answer]</h3>

Given that C is the midpoint of AB so from this result that AC = BC so given that AC = 20 => BC = 20 too
and given that AB = 5x so AB = AC +BC so AB = 20+20 so AB = 40
than AB = 40 and AB = 5x so result 5x = 40 => x = 40/5 so x = 8
hope this will help you
