step-by-step explanation:

hopefully im right

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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)

y/x of point b= y/x of point a

(i got the same question, this was the correct answer.)
