Just use the good old Pythagorean Theorem:

d^2 = ∆x^2 + ∆y^2

= ((3x+1)^2-(2x)^2)+((y-2)-(y-2))^2

= (5x^2 + 6x + 1) - (0)

. . .

what Steve meant to say was:

d^2 = (3x+1 - 2x)^2 + (y-2 - (y-2))^2

= (x+1)^2 + 0^2

d =√(x+1)^2

= x+1

e.g.

let x = 3, y = 5

then T is (6,3) and U is (10,3)

TU = √(4^2 + 0^2)

= √16 = 4

according to my result, d = 3+1 = 4 , as in the test answer.

ouch! Guess I had too many squares working with me!

What was I thinking?
