Rob bought a hat and 3 shirts for $35. Dan bought 2 hats and a shirt for $20, Which system of equations can be used to find s, the cost of one shirt, and h, the cost of one hat?
h + 38 = 35
2h + s = 20
h+ 38 = 35
2s + h = 20
8 +3h = 35
28 th = 20
8 + 3h = 35
2h + 8 = 20

Factor a^3 - 3 + 3a^2 - a. a) (a - 1)(a + 1)(a + 3) b) (a^2 + 1)(a - 3) c) (a^2 - 3)(a + 1)
