Write a method that takes two rectangles and returns the (positive) difference between their areas. This method must be named areaDiff() and have 2 Rectangle parameters. This method must return a double.

For example suppose two Rectangle objects were initialized as shown:

Rectangle rect1 = new Rectangle(2.0, 8.0);
Rectangle rect2 = new Rectangle(6.0, 3.0);
The method call areaDiff(rect1, rect2) should then return the value 2.0.

How is the number 372 written when expanded out to place values in the base 8 (octal) number system? a. 2 x 4 + 3 x 2 + 4 x 1 b. 3 x 64 + 7 x 8 + 2 x 1 c. 3 x 8 + 7 x 7 + 2 x 6 d. 3 x 100 + 7 x 10 + 2 x 1

Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.
