HELP PLEASE 21 POINTs Which model shows two equal expressions when b = 3? A b + b + b = 1 + 1 + 1

B b + b = 1 + 1 + 1 + 1 + 1 + 1

c b + b + b = 1

D b + 1 + 1 + 1 = 1 + 1 + 1 + 1

A maybe?

Step-by-step explanation:

I can't see why it would be any of the other ones.

B

6=6

Step-by-step explanation:

yeah-ya right?

it's d

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
