Answer:
3.2 ft
Step-by-step explanation:
The initial distance from the base of the ladder to the wall is:
![20^2=16^2+d^2\\d=12\ ft](https://tex.z-dn.net/?f=20%5E2%3D16%5E2%2Bd%5E2%5C%5Cd%3D12%5C%20ft)
After moving the ladder, the distance from the base to the wall is 12 - 2x while the height of the ladder is 16 + x. The distance x is given by:
![20^2 = (12-2x)^2+(16+x)^2\\400 = 144-48x+4x^2+256+32x+x^2\\5x^2-16x=0\\5x=16\\x=3.2\ ft](https://tex.z-dn.net/?f=20%5E2%20%3D%20%2812-2x%29%5E2%2B%2816%2Bx%29%5E2%5C%5C400%20%3D%20144-48x%2B4x%5E2%2B256%2B32x%2Bx%5E2%5C%5C5x%5E2-16x%3D0%5C%5C5x%3D16%5C%5Cx%3D3.2%5C%20ft)
Therefore, the top of the ladder is 3.2 ft higher now.
