Compute the permutation. 8 p 4 32 1,680 6,720

ANSWER

EXPLANATION

The given permutation is

Recall the formula for permutation

We substitute n=8, and r=4 to obtain:

Recall the factorial expansion

We apply this expansion to get:

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.

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
