Step-by-step explation:

You have to work this out on paper-at least i did,

I draw a diagram,as always and FINALLY you get the answer

idk how to explain it lol

120

Step-by-step explanation: you do 6 * 5 * 4 * 3 * 2 * 1 / 3 * 2 * 1 = 120

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
