An irregular parallelogram rotates 360 degrees about the midpoint of its diagonal. how many times does the image of parallelogram coincide with its preimage during the rotation

a. 2

b.4

c.6

d.8

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

the answer to this is a. a^2 + b^2 = c^2

in my opinion , its hazel
