The app isn't working for me at all it won't let me scan and keeps saying try again is the app down is anyone else app not working .

answer: the equation matches the regression

step-by-step explanation:

what i would say the best answer is a. 40.5

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)
