Answer:
Option (2) CPCTC
Step-by-step explanation:
In the given regular triangle ADF, all sides and angles of the triangle will be equal
∠A = ∠D = ∠F = 60°
And DE = EF [Since E is the midpoint of side DF]
Statements Reasons
1). ∠D ≅ ∠F Given
2). ∠DBE ≅ ∠ECF Given
3). DE ≅ EF Given
4). ΔDBE ≅ ΔECF By AAS property
Therefore, DB ≅ FC
Option (2) Corresponding parts of the congruent triangles are congruent (CPCTC)
Using the arrangements formula, it is found that 907,200 arrangements can be formed using the letters in the word FORGETTING.
<h3>What is the arrangements formula?</h3>
The number of possible arrangements of n elements is given by the factorial of n, that is:
When there are repeating elements, with the number of times given by , the number of arrangements is given by:
In this problem, the word FORGETTING has 10 letters, of which G and T repeat twice, hence the number of arrangements is given by:

It is a solution, hope this helped
The patient should take 6 tablets of vitamin B12 per day.
Answer:
The solution graph is also attached.
Step-by-step explanation:
Given
as
so
solving the intervals
as
subtract 2 from both sides
also
subtract 2 from both sides
Add 3y to both sides
Divide both sides by 4
so combining the intervals
Merge overlapping intervals
Therefore,
The solution graph is also attached.
