How do u write 100,203 in expanded form

100000+200+3 = 100,203. since there is a lot of zero's, you skip that place value and go on to the next where there is a real number. hope it helps!

i dont get it. where are the "descriptions"?

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
