User: Which of the following equations is quadratic? x(x^2 + 1) = 0 5(4x + 2) = 3 (x + 3)(x + 4) = 5

Weegy: The equation (x + 3)(x + 4) = 5 is quadratic.

User: If (x + 5)(x - 2) = 18, then which of the following statements is true? x + 7 = 0 or x - 4 = 0 x + 5 = 0 or x - 2 = 0 x + 5 = 6 or x - 2 = 3

Weegy: 9(x - 2) = 18 is x = 4.

User: The graph of y = ax^2 + bx + c passes through the points (-2, 0), (0, -2), and (2, 0). Determine the solution set of 0 = ax^2 + bx + c. {-2} {0} {-2, 2} {-2, 0, 2}

Weegy: The graph of y = ax^2 + bx + c passes through the points (-2, 0), (0, -2), and (2, 0). The solution set of 0 = ax 2 + bx + c is {-2, 2}

User: Give the values of a, b, and c from the general form of the equation (2x + 1)(x - 2) = 0. a = 2, b = -3, c = -2 a = 2, b = 5, c = -2 a = 3, b = 1, c = -1

User: The width and the length of a rectangle are consecutive even integers. If the width is decreased by 3 inches, then the area of the resulting rectangle is 24 square inches. What is the area of the original rectangle? 12 square inches 48 square inches 96 square inches

Weegy: The width and the length of a rectangle are consecutive even integers. If the width is decreased by 3 inches, then the area of the resulting rectangle is 24 square inches. What is the area of the original rectangle? B. [ 48 square inches ]

User: What is the solution set of 7x^2 + 3x = 0? {0, 3/7} {0, -3/7} {0, -4/7}

Weegy: The solution set of 7x^2 + 3x = 0 is: B. {0, -3/7}.

User: An object is dropped off a building that is 144 feet tall. After how many seconds does the object hit the ground? (s = 16t^2) 3 seconds 4 seconds 9 seconds

Weegy: 16t^2 = 144 Simplify, divide both sides by 16 t^2 = 9 t = 3 seconds
