Answer:
a.
Box 1: (2w)(w)=338 sq.in.
Box 2: (3w-12)(w)=96 sq.in.
Box 3: (40-w)(w)=384 sq.in.
b.
Box 1: 2w²-338=0
a= 2 b= 0 c=-338
Box 2: 3w²-12w-96=0
a= 3 b=-12 c= -96
Box 3: w²-40w+384
a=1 b=-40 c=384
c.
Box 1:
w=13,-13
Box 2:
w=8,-4
Box 3:
w=24,16
d.
Box 1: w=13
Box 2: w=8
Box 3: w=16
For box 1 and 2:
There is no negative values in measurements therefore the roots that are positive are the widths.
For box 3:
Width is always shorter that the lenght therefore the root with lower value is the width.
e.
Box 1: L=26
Box 2: L=12
Box 3: L=24
Used substitution on the formula for Legth
Step-by-step explanation:
a.
For Box 1 and 2:
The formula for area is (legth)(width)=Area
For Box 3:
Use the formula for perimeter(P=2L+2W) to get the formula for Area
b.
c.
d.
e.
Box 1: L=2(13)
Box 2: L=3(8)-12
Box 3:
L= 40-(16) or you can use the root with higher value from its roots.
