Two sides of a triangle measure 2x – 4 and 7x – 2 units, respectively. which of these is a possible length for the third side of the triangle? a 3xb 6xc 5x+2d 9x-6

Step-by-step explanation:

Given two sides of a triangle 2x – 4 and 7x – 2 units.

Difference of two sides of a triangle is less than third side.

Let us find the difference of 7x – 2 and 2x – 4, we get

7x-2 - (2x-4) = 7x -2 -2x +4

= 5x + 2.

Third side should be less then 5x+2, so 5x+2 can't be third side.

Sum of two sides is greater than third side.

Adding given sides of triangle, we get

7x-2 +2x-4 = 9x - 6.

Third side should be greater than 9x-6. So, 9x-6 can't be third side.

Now, if we add 3x and 2x-4, we get

3x+2x-4 = 5x-4, which is less than 9x - 6.

So, 3x can't be third side.

Therefore, correct option is :

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
