18m² + 16k² is the expression simplified
Janine’s error is that she incorrectly counted the spaces that point C has shifted. Focusing on point C like Janine did, to get to point C’ you would need to shift 3 units to the left and 5 units down. This would make the new translation rule (x-3, y-5) to get from triangle ABC to triangle A’B’C’.
The figure RQTS is a clockwise rotation of figure DEFC, then:
The image of CD is
Answer: Option C. RS
25
-13
which equals 12
This is because the circles have areas of 9
and 4
respectively.
Plus we can tell the square has the area of 100 due to the fact that the diameters of the circles add up to 10, meaning the larger circle has a radius equal to 5 and an area of 25
. Subtract the other two from the larger one and you get your answer.

Step-by-step explanation: There are 26 letters in the alphabet lettered A through Z.
Deepak is given the choice of picking a four letter password of his liking, using any four letters. Since the letters he uses can be repeated, it is 26 * 4 possibilities, since there are 26 different possibilities of letters from the alphabet he could choose, for 4 times. Also, since letters can be repeated, 26 stays the same. If letters could not be repeated, it would be 26 * 25 * 24 * 23.
