Answer:
The answer to your question is Perimeter = 64 ft
Step-by-step explanation:
Data
width = 16 ft
length = width + 4 ft
Perimeter = ?
Process
1.- Calculate the length
Length = 14 + 4 = 18 ft
2.- Look for the formula of the perimeter
Perimeter = 2(length) + 2(width)
3.- Substitution
Perimeter = 2(18) + 2(14)
4.- Simplification
Perimeter = 36 + 28
5.- Result
Perimeter = 64 ft
with the pythagorean theorem

using the formula of the quadratic equation

the length cannot be negative, therefore x=7
length of the shorter leg is: 7ft
length of the longer leg is: 3+3(7)= 24ft
length of the hypotenuse is: 4+3(7)= 25ft
From the graphs you can see that the graph of the line

lies under the graph of the line

. Then all solutions of unequality

are solutions of unequality

, but not all solutions of unequality

are solutions of unequality

.
For example, if x=1, y=-2

.
