The area of the wall is 92,322
The fault line moved a total of one inch it is very easy but your just overthinking it
hope this helps
Every x value should have only one value of y.
So the answer is the last choice.
98 - x² = 0
x² = 98
x = ±√98
Lets factor 98
98 | 2
49 | 7
7 | 7
1
So, 98 = 2 . 7 . 7 = 2 . 7²
x = ±√2.7²
x = ±7√2
