The number is 142
you first make an equation ;
86+x=2x-56
Add 56 to both sides
142+x=2x
Subtract x from both sides
142=x
3 yards = 36*3 = 108 inches
-> total of width and length = 108/2 = 54 inches, because perimeter = 2*total of length and width.
=> length + width = 54 inches
and 6 ≤ width <span>≤ 12
=> all possible dimensions are:
6x48
7x47
8x46
9x45
10x44
11x43
12x42</span>
I am helping my sister learn this right now, so I know what it is :) A man named Pythagoras discovered and interesting thing between all right triangles! The square of the hypotenuse is equal to the sum of the squares of the other two sides! I hope this helps.
Have a wonderful day :)
