If you’re having trouble with your nines times table use the finger trick. But it only works for 9x1-9-10 so hold up your hands in front of you and your palms facing towards you. Since you’re using 9x9 put your ninth finger down and the amount of fingers on your left would be the amount of tens so their would be 8 tens meaning 80 and the amount of fingers on the right side of the finger that is down would be the ones so there is one finger on the right. After that, you can just add them up. 80+1= 81 if you need another example just comment on this and say if you’re confused.:)

How do you connect the ideas of congruency and rigid motion?
natta225 [31]
<span>Rigid motion does not change the shape of an object. if you move an object to another place, you can think of it as a new object (a copy) at the new position and it will be congruent to the object at the original position. or, if two objects are congruent, you can move one object so it lies on top of the other, showing they are congruent.</span>

Need help with 35 thank you so much!!
Yakvenalex [24]

If a pentagon is regular, then all of the sides are the same length. This means that

5x-4=2x+11 \iff 5x-2x = 11+4 \iff 3x=15 \iff x = 5

So, if x=5, the lengths of the sides evaluate to

5x-4 = 25-4=21,\quad 2x+11=10+11=21

So, all the sides of the pentagon are 21 units long, and AB is 21 units long as well, because all sides are the same length.
