Answer:

So the width is 3.25

Step-by-step

If the perimeter of a rectangle is 300 and the length is two times the  

width, what are the length and the width?

• Call the width of the rectangle x.  Then, if the length is three times  the width, the length must be 3x.  
• Now, if you have a rectangle whose  width is x and whose length is 3x, the perimeter must be  3x + 3x + x + x = 8x.  
• You are told that the perimeter is 26, so the equation is 8x = 26.  
• Dividing both sides by 8, one gets x = 3.25.  So the width is 3.25 and the  length is 6.5.

Final answer:

Given the length is 3 more than the width, and the perimeter is 26 inches, by solving the equation corresponding to the perimeter of the rectangle, we find that the width of the rectangle is 5 inches.

Explanation:

The question is asking for the width of a rectangle given that its length is 3 more than its width and the perimeter is 26 inches. Let's denote the width as x. Therefore, the length is x + 3.

The formula for the perimeter of a rectangle is 2*(length + width), which in this case translates into 2*(x + (x + 3)). As given, this equals 26. Solving the equation 2*(2x + 3) = 26, we find that x = 5. Therefore, the width of the rectangle is 5 inches.

The length of the middle segment RS is determined as 18.

How to calculate the middle segment?

Let's assume that the three consecutive even integers are x, x + 2, and x + 4

So, the length of PR (x) + the length of RS (x + 2) + the length of SQ (x + 4) equals the total length of PQ (54).

Mathematically, this can be represented as:

x + (x + 2) + (x + 4) = 54

Now, let's solve for x:

3x + 6 = 54

Subtract 6 from both sides:

73x = 48

Now, divide by 3:

x = 16

So, the first even integer (PR) is 16, the second even integer (RS) is 16 + 2 = 18, and the third even integer (SQ) is 16 + 4 = 20.

Thus, the length of the middle segment RS is 18.

Answer:

RS = 18

Step-by-step

PR = x

RS = x+2

SQ = x+4

x+(x+2)+(x+4)=54

3x+6=54

3x=48

x=16

PR = 16

RS = 18

SQ = 20

Answer: 2x+21

=============================

Work Shown:

f(x) - g(x) = [ f(x) ] - [ g(x) ]

f(x) - g(x) = [ 7x+15 ] - [ 5x-6 ]

f(x) - g(x) = 7x+15 - 5x+6

f(x) - g(x) = (7x-5x)+(15+6)

f(x) - g(x) = 2x+21
