<span>The correct answer is 11 ft.
Explanation:
The diagonals of a parallelogram bisect each other. This means that the portion marked x+4 is the same length as the portion marked 2x-7; this gives us the equation x+4=2x-7.
Subtract x from each side:
x+4-x=2x-7-x
4=x-7.
Add 7 to both sides:
4+7=x-7+7
11=x</span>

Answer:
![-2\sqrt{5}](https://tex.z-dn.net/?f=-2%5Csqrt%7B5%7D)
Step-by-step explanation:
![\sqrt{20} = \sqrt{10*2} = \sqrt{5 * 2 *2} = \sqrt{2^2 * 5} = 2\sqrt{5} \\\\\sqrt{80} = \sqrt{20*4} = \sqrt{5*4 *4} = \sqrt{4^2 * 5} = 4\sqrt{5} \\\\2\sqrt{5} - 4\sqrt{5} = -2\sqrt{5}](https://tex.z-dn.net/?f=%5Csqrt%7B20%7D%20%3D%20%5Csqrt%7B10%2A2%7D%20%3D%20%5Csqrt%7B5%20%2A%202%20%2A2%7D%20%3D%20%5Csqrt%7B2%5E2%20%2A%205%7D%20%3D%202%5Csqrt%7B5%7D%20%20%20%5C%5C%5C%5C%5Csqrt%7B80%7D%20%3D%20%5Csqrt%7B20%2A4%7D%20%3D%20%5Csqrt%7B5%2A4%20%2A4%7D%20%3D%20%5Csqrt%7B4%5E2%20%2A%205%7D%20%3D%204%5Csqrt%7B5%7D%20%20%20%5C%5C%5C%5C2%5Csqrt%7B5%7D%20-%204%5Csqrt%7B5%7D%20%3D%20-2%5Csqrt%7B5%7D)
