You would have to count the faces of cubes after you’ve joined them and then add all the surface areas up of each individual cube . I drew a pic to help you
1 unit left and reflection across x axis
Y = 2x - 2 ⇒ 2x - y = 2 ⇒ 2x - y = 2
y = x + 2 ⇒ x - y = -2 ⇒ <u>2x - 2y = -4</u>
<u>3y</u> = <u>6</u>
3 3
y = 2
2x - 6 = 2
<u> +6 +6</u>
<u>2x</u> = <u>8</u>
2 2
x = 4
(x, y) = (4, 2)
