Using the Parallelogram Side Theorem Parallelogram A B C D is shown. Sides A B and D C are parallel. The length of A B is 4 q mi

ipn [44]

Answer: The length of AB = 8 units

Step-by-step explanation:

Given: In parallelogram ABCD, Sides A B and D C are parallel.

The length of AB is 4q minus 8 and the length of DC is q + 4.

Since opposite sides of parallelogram is parallel and equal.

So $4q-8=q+4$

$\Rightarrow\ 4q-q=4+8\\\\\Rightarrow\ 3q=12\\\\\Rightarrow\ q=4$

Length of AB = 4q-8=4(4)-8=16-8=8 units

Hnece, the length of AB = 8 units

If a quadratic equation has a discriminant that equals zero, which of the following statements is always true?

kotegsom [21]

Answer:

d. The equation has one solution and there is not enough information to determine the direction of the parabola.

Step-by-step explanation:

For a general quadratic equation

y = ax² +bx +c

the solution is

$x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

The discriminant (D) is the part of the quadratic formula underneath the radical: b² - 4ac.

D tells us whether there are

two different real solutions
two identical real solutions ("one solution")
two complex solutions.

If D= 0,

$x = \dfrac{-b}{2a}\pm0 = \mathbf{\dfrac{-b}{2a}}$

and there are two identical solutions ("one solution").

The direction of the parabola depends on the sign of a.

That information is not given, so we cannot determine the direction of the parabola.
