-14rst + 22r²s - 4rs²t = Don’t forget to take out the numerals and symbols

Its easy but each Time I do It It says its wrong(((

Step-by-step explanation:

-14rst + 22r²s - 4rs²t = -2 * 7 * rst + 2 *11 *r²s - 2 * 2 rs²t

                                 = -2rs [ 7t  -11r + 2st ]

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

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)
