Answer:

<h2>The lenght is 17 miles</h2><h2>The wide is 13 miles</h2>

Let / l : the lenght of the rectangle

w : the wide of the rectangle

Step-by-step explanation:

a = l \times w \\ 221 = (w + 4) \times w \\ 221= w^{2}  + 4w \\  {w}^{2}  + 4w - 221 = 0 \\ (w + 17)(w - 13) = 0 \\ either \: w  + 17 = 0 \\ so \: w =  - 17 \: mile \:  \:  \:  \: neglect \\ or \: w - 13 = 0 \\ so \: w = 13 \\ l = w + 4 \\ l = 13 + 4 = 17 \: mile

I hope that is useful for you

Solve 2x + 5y = −13 3x − 4y = −8
zlopas [31]
If you would like to solve 2x + 5y = -13 and 3x - 4y = -8, you can do this using the following steps:

2x + 5y = -13       /*4
3x - 4y = -8         /*5
_______________
8x + 20y = -52
15x - 20y = -40
_______________
8x + 15x + 20y - 20y = -52 - 40
23x = -92
x = -92 / 23
x = -4

<span>3x - 4y = -8 
</span>3 * (-4) - 4y = -8
-12 - 4y = -8
12 + 4y = 8
4y = 8 -12
4y = -4
y = -1

The correct result would be x = -4 and y = -1.
