Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term. 3, 6, 9, 12, ...​

boxplot

step-by-step explanation:

the true ones are a b and d

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)
