Answer:
D (10)
Step-by-step explanation:
The difference in the x-values is 8 and the difference in y-values is 6; if we draw a line for each difference and connect the points, we get a right triangle. Use pythagorean's theorem of a^2 + b^2 = c^2; 36 (6^2) + 64 (8^2) = 100 (10^2). Square root 100 to get 10
Square root of x^2 is x
square root of 144 is 12
(x-12) (x+12)
x=12 or x= -12
