The length that results in the maximum area is 39 feet.
<u><em>Explanation</em></u>
Lets assume, length of the rectangle is 
feet and width of the rectangle is 
feet.
As the length and width must add up to 78 feet, so the equation will be...
Solving equation (1) for y : 
Now the area of the rectangle,
will be maximum when 
Now taking derivative of equation(2) with respect to ......
If 
, then
If 
, then 
So, both length and width will be 39 feet for getting maximum area.
The length that results in the maximum area is 39 feet.

Consider the following ordered pairs that represent a relation. {(–4, –7), (0, 6), (5, –3), (5, 2)}
Domain : {–4, 0, 5 }
Range: {( –7, –3, 2, 6}
By the definition for the absolute value,
So for the compound function

Answer:
127
Step-by-step explanation:
The angles add up to 180° since they are on a straight line. Find 3x - 5.
3x - 5 + x + 1 = 180
4x - 4 = 180
4x = 180 - 4
= 176
x = 176 ÷ 4
x = 44
3x - 5 = 3(44) - 5
= 132 - 5
= 127
