Determine which statement completes each open sentence:

Answer/Step-by-step Explanation:

Solve, simplify and substitute the value of x in each case, where applicable and see if both sides of the equation are equal or not:

1. 3(x - 4 + x) 3x - 4 + x

When x = 4. Substitute x = 4

3(4 - 4 + 4) 3(4) - 4 + 4

3(4) 12

12 12

Therefore,

3(x - 4 + x) is equal to 3x - 4 + x

2. 4² 4•2

4•4 4•2

16 8

Therefore,

4² is NOT equal to 4•2

3. 32 ÷ 8 + 1 3² - 1

32 ÷ 8 + 1 3² - 1

Divide first and take exponent

4 + 1 9 - 1

5 8

Therefore,

32 ÷ 8 + 1 is NOT equal to 3² - 1

4. 3(x - 4 + x) 3x - 4 + x

When x = 2. Substitute x = 2

3(2 - 4 + 2) 3(2) - 4 + 2

3(0) 6 - 2

0 4

Therefore,

3(x - 4 + x) is NOT equal to 3x - 4 + x

5. 15 ÷ (1 + 2) 15 ÷ 1 + 2

Perform addition inside the parentheses first on your left then divide 15 by 1 on your right first

15 ÷ 3 15 + 2

5 17

Therefore,

15 ÷ (1 + 2) is NOT equal to 15 ÷ 1 + 2

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.
