When completing the square <span>x=9.12311 and </span><span>x=<span>0.876894</span></span>
Long Piece: x + 18
Short Piece: x
(x) + (x + 18) = 84
2x + 18 = 84
2x = 66
x = 33
Long Piece: x + 18 = (33) + 18 = 51

<u>Trigonometric identities</u>
<u />

Therefore, using the <u>identities</u>, the given expression can be <em>simplified</em> as follows:

Regroup terms:
y - 2/9 ≤ 5/9
Add 2/9 to both sides:
y ≤ 5/9 + 2/9
Simplify 5/9 + 2/9 to 7/9:
y ≤ 7/9
