The area of a rectangle is 72cm2, in which the width is twice the length. what are the dimensions

Dimension: 2inches by 4 inches

Step-by-step explanation:

Given

Required

Determine the dimension.

This is calculated as :

So:

Substitute 72 for A

Divide bith sodes by 2

Take square root of both sides

Recall that:

Hence:

Hence, the dimension is: 2 by 3 inches

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.
