A.
let the number be n.
2n+5=45
2n=40
n=20
A reasonable estimate would be 180 students with blue eyes
Answer and Explanation:
The line seems to pass trough the points (0,6) and (-3,4).
Slope is: 

The slope of the line should be
.
V=LWH
h=10
V=360
360=LW10
divide both sides by 10
36=LW
try some values
ok so if we get L=1 and W=36, that is the same box as L=36 and W=1
so
L,W
36,1
18,2
12,3
9,4
6,6
5 of them
answer is 5 different boxes
dunno what the 'compare volume' is
