Hello May! Concepts for May 2nd

Algebra I

Today we discussed
Today we talked about the Pythagorean theorem and the relationships between the legs of a right triangle and its hypotenuse.  In addition, we worked on simplifying radical expressions using the product and quotient properties of square roots.
