20 - 12/x = 16 ; x = 3

20−12/3=?16

16=16

True

Step-by-step explanation: hope this help:)

20-12 = 8.

If 8 / x = 16, then 3 at x;

8/3 =16.

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)
