Asquare has a diaginal of 18 millimeters what are the perimeters

Since it is a square, the two sides that will form the right triangle with the diagonal is equal. Use the Pythagorean theorem. Hence, x² + x² = 18² , x = ± 9√2, and since it is a square it can't be a negative number, so x= 9√2 milimetres

The question is asking for perimeter, and a square has 4 equal sides. 9√2 × 4 = 36√2 milimetres

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.
