Q:

Simplify: 4 - (3 + 1)2 - 6 ÷ 2 + 4 Combine like terms: 7x3 + 2x - 5x2 + 6 + x + 9 + 3x3 + 12x2 Simplify: (2x5 - 3x2 + 4) - (x5 + 2x2 + 7) Multiply: 3x2(4x3 - 2x2 + 7x - 4) Evaluate: 6x2 + 9x - 7, when x = 2 Evaluate: 3(x - y)2 + 4y - 6x + 2, when x = -1 and y = 3 Solve for x: 7x - 5 = 23 Solve for y: 7y - 4 + 3y + 6 = 9y + 8 Solve for w: 5(w - 2) + 6 = 3w - 14 Solve the following inequality for x. Then graph the solution on a number line: -4x + 2 < 2x - 6
