It take 8.205 minutes to fill a queen sized mattress.
<h3>What is volume?</h3>
'Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
Given dimensions:
Twin sized air mattress (39 by 8.75 by 75 inches).
Queen sized mattress (60 by 8.75 by 80 inches)
Now, Volume of twin sized mattress
=39* 8.75* 75
= 25593.35 cubic inch
Volume of queen sized mattress,
=60* 8.75* 80
= 42000 cubic inch
as, To fill 25593.35 cubic inch it takes 5 minutes
so, to fill 1 cubic inch = 5/25593.35
and, So to fill 42000 cubic inch it will take = 42000* 5/25593.35
=8.205 minutes

Answer:
-2x^2-20x-46
Step-by-step explanation:
-2(x^2)-20x-46
-2(x^2) -2(10x)-46
-2(x^2)-2(10x)-2(23)
-2(x^2+10x)-2(23)
-2x^2-20x-46
