Hillgrove high school plays 3 soccer games. the team loses 2 of those games. according to the tree diagram, how many ways could this happen?

The figure above shows the lengths of thesides of a rectangle in cm. find the valuesof x and y and then the area of the rectangle.sides: top= 3x - yleft= 3y + 4bottom= 2x + yright= 2x - 3 use both methods, elimination and substitution, if possible.

What is the difference between the predicted value and the actual value

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).
