What is the difference?

StartFraction x + 5 Over x + 2 EndFraction minus StartFraction x + 1 Over x squared + 2 x EndFraction
StartFraction x squared + 4 x minus 1 Over x (x + 2) EndFraction
StartFraction x squared + 4 x + 1 Over x (x + 2) EndFraction
StartFraction 4 Over negative 1 (x squared + x minus 2) EndFraction
StartFraction x squared + 6 x + 1 Over x (x + 2) EndFraction

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)

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram
