The length of a rectangle is 12 ft. longer than twice its width. If the total length of a width and a length is 44 ft., what is

REY [17]

Width of the rectangle is 10.67 ft

Step-by-step explanation:

Step 1:

Let the width of the rectangle be x. Then length = 2x + 12

Given width + length = 44ft ⇒ x + 2x + 12 = 44

⇒ 44 = 3x + 12

⇒ 32 = 3x

⇒ x = 32/3 = 10.67

Width of the rectangle = 10.67 ft

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:

$4x^2 + 22x + 15$
