You want the (positive) distance when the height is 0, 0= -d^2 + 10d +5.
You would factor that out(You'd get radicals), and the final answer would be
<span>5±<span>30<span>−−</span>√</span></span><span>
You'd take the only positive one of the two, 5 + srt(30)
I hope I did that right :/</span>

A vat of water and a weighing scale
Answer:
Option (c) "
"
Step-by-step explanation:
The given equation is :
q = c4(h + r)
We need to solve it for r.
Dividing both sides of the given equation by 4c.
Now, subtract h both sides of the equation.
Hence, this is the required solution.
Step-by-step explanation:
(x + 12)(x - 6)
x2 - 6x + 12x - 72
x2 + 6x - 72
