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

y(y + 4) - y = 6

y^2 + 4y - y = 6

y^2 + 3y = 6

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

1 Answer/Comment

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.

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)
