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.

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.

(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)
