this lesson is dividing decimals by decimals

answer:

The dividened and divisor were both multiplied by 10.

The quotient of both expressions is 4.

Step-by-step explanation:

8.4 x 10 = 84.

2.1 x 10 = 21.

8.4 / 2.1 = 84 / 21.

8.4 / 2.1 = 4.

84 / 21 = 4.

Hope this helps.

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.
