P(x) = x3= 5x3 + 9x2-x+3; binomial: X+3

9x

Step-by-step explanation  

"{x + 3 = 0, 3 x^2 = 1, 5 x^3 = 3, x (9 x + 1) = 0, 5 x^3 + x = 0, 5 x^2 = 9 x}

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
