A circle with radius 1 passes through two vertices of a square, as shown in the picture. If the red area is equal to the blue area, what is the area of the square?

Point E is the midpoint of the side BC of triangle ABC and F is the midpoint of AE. The line through BF intersects AC at D. Find the area, in cm squared, of triangle AFD if the area of the triangle is 48 cm²

Tony rode a bicycle from A to B in 36 km/h. After that, Tony went back from B to A in 48 km/h. It took 3 and a half hours to go from A to B and back to A. Assuming that Tony never have any rest, what is the distance between A and B?

Ich schlage vor, dass du die Aufgabe noch einmal fehlerfrei mit allen Angaben aus deinem Buch abschreibst.

Was bedeutet:"der quadar masse sind . 3a "?

Es handelt sich um den Binomischen Lehrsatz, der mit vollständiger Induktion bewiesen werden soll.

In diesem Video wird jeder Induktionsschritt voll gut erklärt:

80km/h*0.5h+100km/h*0.5h=40km+50km=90km     (30min=0.5h)

x/13 = 3/58

x = 3*13/58

x = 0.6724 m = 67.24 cm

x² - 3x + 7 = 3x - 2

x² - 6x + 9 = 0

(x - 3)(x - 3) = 0

                 x = 3

3*3 - 2 = 7     (3,7)
