A quadrilateral is plotted on the coordinate plane. Each of its vertices undergoes the same transformation. Which rule below does NOT preserve the length of the sides of the quadrilateral?
(x, y) + (x + 2 y + 5)
(x, y) + (-x-2.y-3)
O
(x, y) → (3x - 2.y-3)
(x, y) + (-x-2, -y-3)

ok then what happened.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

answer is  

a.

7 in. x 11 in.

hope you get this right.
