Damion · Answer 1

(1+w) is the right answer

Andreas Nielsen · Answer 2

1) p = 4I + 4w + 4h = > 2) Subtract 4I + 4W fromt both sides = > p - 4W - 4I = 4h = > 3) divide both sides by 4 = > [p - 4I - 4W] / 4 = h. So, the subtraction of 4I and 4 W from both sides is followed by the division by 4 in tthw two sides, resulting in h = [p - 4I - 4W] / 4, which is equivalent to (p / 4) - (I+W).
