2. I'm assuming you meant:
-3(-9) - [-5-3] =
27 - 8 = 19.
3. 9c^3 + 7c -(3c^3-12+c) =
9c^3 + 7c - 3c^3 + 12 - c =
6c^3 + 6c + 12 =
6(c^3 + c + 2).
4. Similar to # 3.
5. x = 1/25(22x - 9w) =
Multiply both sides by 25:
25x = 22x - 9w,
25x - 22x = 9w,
3x = 9w,
X = 3w.
6. -14x - 7(4-7) < (2x-15)
-14x + 21 < 2x-15
-14x - 2x < -15 - 21,
-16x < -36,
X > -36/-16,
X > 2 1/4.

7. 0.08 * $413 = $33.04
8. Width = X-Met3rs.
Length = (x+8) Meters.
2x + 2(x+8) = 108m.
2x + 2x + 16 = 108,
4x = 108 - 16 = 92,
X = 23m = Width.
X+ 8 = 31m = Length.
9. 0.1x + 300 > 0.03x + 500,
0.1x - 0.03x > 500 - 300,
0.07x > 200,
X > 2857 Copies.
