What is the answer for 12d=3?

d= 1/4

Step-by-step explanation:

d = -9

Step-by-step explanation:

12d=3

minus 12 from both side is d= -9

for proof that -9 is correct just insert it in  12-9=3 and 12-9 is 3

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)
