Find: (4x2y3 + 2xy2 – 2y) – (–7x2y3 + 6xy2 – 2y) Place the correct coefficients in the difference.

sounds & other waves originate from any vibrating object

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)

1/4 is the asnwer cuz 5/20 is the faction
