The maximum area of the rectangular path is when the length is 24 feet and the width is 12 feet.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the length and y represent the width. Hence:
There is 48 feet of fencing:
x + 2y = 48
x = 48 - 2y (1)
The area (A) is:
A = xy = y(48 - 2y)
A = 48y - 2y²
The maximum area is at A' = 0, hence:
48 - 4y = 0
y = 12
x = 48 - 2(12) = 24
The maximum area of the rectangular path is when the length is 24 feet and the width is 12 feet.

Answer:
The difference between the total and lateral surface areas of the room is 42 square yards.
Step-by-step explanation:
The lateral surface area of an object is the surface area of everything EXCEPT for the top and bottom of the object.
2(6*4.2) + 2(4.2*3.5) = 79.8 square yards
The total surface area of an object is everything INCLUDING the top and bottom of the object.
79.8 + 2(6*3.5) = 121.8 square yards
121.8 - 79.8 = 42 square yards
C is FALSE
the set of whole numbers is { 0, 1, 2, 3, 4 , ......}
the set of integers is { ..., - 2, - 1, 0, 1, 2, 3, ......}
As we can see the set of whole numbers does not include negative numbers, thus integers are not a subset of whole numbers
However, whole numbers are a subset of integers.
