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

Given are:
250 adults and 180 parents
so we can solve the number of not parents
not parents = 250 - 180
not parents = 70
then we can number of people of votes for no
no not parents = 70 - 40 = 30
no parents = 180 - 150 = 30
yes no
parents 150 30
not parents 40 30
Did you try to attach anything?? can you give me the choices at least? i want to help but i dont know your question..

Step-by-step explanation:
Let's organise our information :
- the radius of the circle is r=14 cm
- we can get the area of the shaded by substracting the area of that triangle from that quarter
The area of the cercle's quarter area is :
The area of the triangle is :
NOw the area of the shaded segment :
