answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
