Answer:

Step-by-step explanation:
The side length of a square is represented by the expression 2x + 5.
The area of a square is given as:

where a = length of side of the square
The area of the square is therefore:

The perimeter of a square is given as:

The perimeter of the square is therefore:

The difference between the area of the square and the perimeter of the square is:

The expression that represents the difference between the area and the perimeter of the square is:

Answer:
C
Step-by-step explanation:
Since this is an indererminate form, use L'Hopital
d(sint)/dt = cos(t)
d[ln(2e^t) - 1] = (2e^t)/[2e^t - 1]
As t --> 0,
cos(0) = 1
(2e^t)/[2e^t - 1] = 2
1/2 is the limit
Perimeter is the sum of the 3 sides:
11 + 15 + 14 = 40 cm.
Area is 1/2 x height x base:
1/2 x 13.4 x 11 = 73.7 square cm.
That would be the median I think...
