HELP ME PLEASE 10 POINTSS !!

Step 1

Step-by-step explanation:

Taylor should have distributed 7 to both numbers in the parenthesis.

So it would be 7y + 31.5 = 32.5

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.

a² + b²= c²

24² + 7² = c²

c= 25
