9- x=20 20 divided by 2 equals 10. 10+8=18
10- I would say that x=3 because 3x3=9. If you add 9 and 12 together it’s 21. 21 is less than 64.
Hope that helps!
the answer is negativepositive
Each loop is of a different size, so we can't rotate the figure some angle x to have it line up with itself (0 < x < 360). Therefore, it doesn't have any rotational symmetry. That rules out choice A and choice C. Point symmetry is the same as saying "rotational symmetry of 180 degrees"
The figure doesn't have any line symmetry either. There is no line we can draw and reflect the figure over to have it match up with itself. That rules out choice B and points to choice D
Answer: D) It has no reflectional symmetry.
Answer:
slope of 9
Step-by-step explanation:
parallel means never touching, so it would have the same slope.

It is 3 meters for each piece and in centimeters, that would be 300.
