48 of the pizzas would be cheese because you divide 80 by 5 and get 16 then multiply that by 3 to get 48
Looks like the graph is decreasing to me
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>
=12-5=7
=21-12=9
when u look at they have a diffrence of 2 so the answer will have a diffrence of 2 =11
1/6 for the first question and 1/3 for the second
