y(y + 4) - y = 6 is a quadratic equation is true.
y(y + 4) - y = 6
y^2 + 4y - y = 6
y^2 + 3y = 6

The true statement about the graph of x < 4 is: open circle on 4 and all numbers to the left shaded
The height of a triangle is 4 more than the base, and the area of the triangle is 6 square units. Find the length of the base. Let x = the length of the base.
Question
Updated 11/17/2014 12:47:25 AM
Let x be the length of the base. Its height is x + 4.
Area = 1/2 * base * height = 1/2 * x * (x + 4) = 6
x^2 + 4x = 6(2) = 12
x^2 + 4x - 12 = 0
(x + 6)(x - 2) = 0
x = -6 or x = 2
The base of the triangle is 2 units.

The minimum height for riding on the Super Screaming Spinner at the theme park is 52 inches. Which of the following expressions shows the height to ride?
Weegy: C. H > 52. The height has to be 52 inches or greater to ride. Technically, this should have a line under the inequality. User: Solve 5x + 7 > 17. Weegy: 5x + 7 > 17 5x > 17 - 7 5x > 10 x > 10/5 x > 2 User: 50 15x User: x + 17 -3 Weegy: -3(x ? 4) > 4(x + 3) -3x + 12 > 4x + 12; -3x - 4x > 12 - 12; -x > 0; x User: Solve 2x - 8 User: Solve 3(x - 2) Weegy: 5(x - 3) + 4(x + 3) = 3(x - 1) 5x - 15 + 4x + 12 = 3x - 3; 5x + 4x - 3x = -3 - 12 + 15; 6x = 0; x = 0 User: Write the quadratic equation in general form and then choose the value of "b." (2x - 1)(x + 5) = 0 Weegy: The quadratic equation (2x - 1)(x + 5) = 0 in general form is: 2x^2 + 9x - 5. In the form ax^2 + bx + c = 0, b = 9. User: Twenty pounds of a salt-water solution contains fifteen percent salt. How much salt is in the water? Weegy: 15% of 20 is 3, so twenty pounds of a salt-water solution that contains fifteen percent salt contains 3 lb of salt. User: Factor p 2 - 8p - 20. Weegy: 3. (p - 10)(p + 2) is the answer. p^2 - 8p - 20 = (p - 10)(p + 2) User: {x | x I, x 3} Weegy: |x| = x is TRUE. (More)
