The given phrase on translation to math expression is (6 ÷ 3) + 12 , the correct option is (a) .
In the question ,
an mathematical phrase is given , that is "Twelve more than the quotient of six divided by three" .
we have to translate it into mathematical expression ,
So , the term quotient of six divided by three is written as 6 ÷ 3 .
and phrase " more " is represented by " + " ,
Hence the given phrase, "Twelve more than the quotient of six divided by three" is (6 ÷ 3) 12 .
Therefore , The given phrase on translation to math expression is (6 ÷ 3) + 12 , the correct option is (a) .
The given question is incomplete , the complete question is
Translate the phrase into a math expression , "Twelve more than the quotient of six divided by three" .

Answer: The correct option is figure (1).
Explanation:
Reason for correct option:
The figure (1) shows the reflection across the side XY followed by reflection across the side YT.
When we reflect the triangle XYZ across the side XY we get the triangle XYT as shown in below figure.
After that we reflect the triangle XYT across the side YT and we get the triangle PYT.
Therefore, only figure 1 shows the triangle pairs can be mapped to each other using two reflections.
Reason for incorrect options:
The figure (2) shows the rotation of 180 degree along the point y.
The figure (3) shows the reflection across the side XY followed by the translation.
The figure (4) shows the reflection, followed by rotation , followed by translation.
