Recall:

if we have a quadratic equation, , where , and are real numbers and , .

Given:

Solving for :

Solving with the positive value:

Solving with the negative value:

i think the answer is d im not sure

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)
