For the element to be congruent only rotations, reflections or translations are allowed to be applied
1)
(x, y) → (x, –y)=reflection
(x, y) → (x + 5, y)=translation
(x, y) → (–x, y)=reflection
->is congruent
2)
(x, y) → (x + 1, y)=translation
(x, y) → (–x, –y)=reflection
(x, y) → (2x, y)=scaling->can't be congruent
3)
(x, y) → (0.5x, 0.5y)=scaling->can't be congruent
(x, y) → (x, –y)
(x, y) → (x, y + 8)
4)
(x, y) → (x – 4, y)=translation
(x, y) → (x, y + 3)=translation
(x, y) → (3x, 3y)=scaling->can't be congruent
so 1) is the only series of transformations with a congruent solution
Hello!
You have to find out how many cubes are in 1 layer
You do this by multiplying the amount across by the amount along the side.
12 * 6 = 72
Divide this by the amount of cubes
288 / 72 = 4
There are 4 layers
The answer is 4
Hope this helps!

Answer:
Answer: 5/9 as a decimal is 0.556.
Answer: -136
Step-by-step explanation:
123+13 is 136 you then change 136 into a negative since you were subtracting 123 from -13
