R is 34.
Cross multiply, and isolate the variable.
The shapes are irregular and is formed by a octagon and a rectangle (square kinda = rectangle)
But given your multiple choice...
1) Shape 1 and 2 isn't congruent so false.
2) Shape 1 and 2 don't share the same coordinates because of a prior translation so false.
3) Shape 1 and 2 isn't congruent so false.
4) Shape 1 could be translated onto shape 2, but it still would not be congruent, so true.
Therefore the 4th one is true.
We need a picture. What are the answer choices
I believe the answer might be 144
ANSWER
{},{1}
EXPLANATION
The given set has one element. So it has
subsets.
These are,
{} and {1}.
That is, the null set and the set itself.
Remember that, the null set is a subset of every set and every set is a subset of itself.
