In boys' clothing, the "7" size typically refers to a standard fit for boys aged 7, while "7x" is designed for boys who are slightly taller or heavier than average for that age, often providing a roomier fit. The main difference lies in the cut and proportions, with "7x" offering additional length and width. This allows for a better fit for boys who may need more space in specific areas, such as the waist or torso. Always check specific brand sizing charts, as measurements can vary.

The width to length ratio is 5 to 7 so if the width is 5x feet then length is 7x feet (x may be fractional). Then perimeter = 2*(W + L) = 1536 ie W + L = 768 is 5x + 7x = 768 or 12x = 768 so that x = 64 Then width = 5x = 5*64 = 320 feet and length = 7x = 7*64 = 448 feet
Without knowing the value of x and the required unit of length then a meaningful answer to this question cannot be provided.
To find the perimeter of a rectangle, you use the formula ( P = 2 \times (\text{length} + \text{width}) ). Given the length is ( 2x + 4 ) and the width is ( 7x - 3 ), the perimeter can be calculated as follows: [ P = 2 \times ((2x + 4) + (7x - 3)) = 2 \times (9x + 1) = 18x + 2. ] Thus, the perimeter of the rectangle is ( 18x + 2 ).
7x is a little longer
The area of square is : 49.0

You're asking for the difference: (3x + 2) - (5 - 7x).(3x + 2) - (5 - 7x) =3x + 2 - 5 + 7x =10x - 3.It is (10x - 3) greater.

Find the volume of the rectangular solid whose length is 3, width is 7x, and height is y. Be sure to include units.
A 7X is a little bit longer and a little bit wider than a 7, but it's not enough to make it an 8.

Let's denote the number of boys as 5x and the number of girls as 7x, where x is a positive integer. Since there are 6 more girls than boys, we have the equation 7x = 5x + 6. Solving for x, we get x = 3. Therefore, the total number of students in the class is 5x + 7x = 12x = 12 * 3 = 36 students.
