The side length of a square is represented by the expression 2x + 5. Which expression represents the difference between the area
musickatia [10]

Answer:

4x^2 + 22x + 15

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:

A = a^2

where a = length of side of the square

The area of the square is therefore:

A = (2x + 5)^2\\\\A = (2x + 5)(2x + 5)\\\\A = 4x^2 + 20x + 25

The perimeter of a square is given as:

P = 4a

The perimeter of the square is therefore:

P = 4(2x + 5) \\\\P = 8x + 10

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

4x^2 + 30x + 25 - (8x + 10)\\\\4x^2 + 30x + 25 - 8x - 10\\\\4x^2 + 30x - 8x + 25 -10\\\\4x^2 + 22x + 15

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

4x^2 + 22x + 15

PLZ HELP ME <br> I appreciate any help, especially if you can show me how you got the answer
Arte-miy333 [17]

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

5.) Find the perimeter and area of a triangle with a base of 11 cm, height of 13.4 cm, and sides of 15
adelina 88 [10]

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.
