Solving the equation 
using completing square method we get 
So, Option A is correct.
Step-by-step explanation:
We need to solve the equation using completing square method.
Solving using completing square method
For completing the square we need to make formula a^2-2ab+b^2=(a-b)^2
Divide the equations by 2
Adding and subtracting (3)^2 on both sides.
Solving the equation using completing square method we get
So, Option A is correct.

Step-by-step explanation:
Triangles are said to be congruent if they have the same sides and the same angles.
The following measures are used to determine if triangles are congruent:
1) Angle-side-angle: If two angles and a side of a triangle is equal to two angles and corresponding side of another triangle, then they are congruent.
2) Side-side-side: If all three sides of a triangle is equal to three sides of another triangle, then the two triangles are congruent.
3) Side angle side: If two sides and an included angle of a triangle is equal to the two sides and corresponding angle of another triangle, then they are congruent.
4) Hypotenuse - leg: If the hypotenuse and one leg of a triangle is equal to the hypotenuse and leg of another triangle then they are congruent.
From the triangles DEF and ABC, already, they already have one equal triangle that is ∠F = ∠B and an equal side i.e DF = AC.
To satisfy congruence, two sides and an angle have to be equal, therefore if AB = DE then the two triangles would be congruent
Using absolute value, it is found that:
- The situation is described by the following equation:
- The markings should be between 45.5mm and 48.5mm.
---------------------------
The definition of the <em>absolute value function</em> is as follows:
----------------------------
The length should be set to 47mm with an allowance of 1.5mm, which means that <u>the absolute value of the difference between the length and 47 should be 1.5</u>, thus:
----------------------------
The solutions are:
The markings should be between 45.5mm and 48.5mm.

I am not posotive about this but I am going to try. I think you can use doubles by like putting it into groups of 4 and then make sure you a total of 32.
