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.
7x - 8 = 2 7x = 10 x = 10/7
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.
12x+2

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.
