P = 2l + 2w
p - 2w = 2l
l = p-2w/2
It would be the third response
Answer:
9
Step-by-step explanation:
You add 6 in each side to get the 4 which means x is the equal to 4
Answer:
a
Step-by-step explanation:
you have to find the hole volume of the other shapes.
Let W = width of package
Let H = height of package
Let L = length of package
The perimeter cab be one of the following:
P = 2(L + W), or
P = 2(L + H)
The perimeter of the cross section cannot exceed 108 in.
When the width is 10 in, then
2(L + 10) <= 108
L + 10 <= 54
L <= 44 in
When the height is 15 in, then
2(L + 15) <= 108
L + 15 <= 54
L <= 39 in
To satisfy both of these conditions requires that L <= 39 in.
Answer: 39 inches
