Ryan's math blog post

Today we learned about triangles.

Scalene: all sides, all angles are different

Isosceles: 2 sides, 2 angles the same

Equilateral: all sides, all angles the same

An example of finding the area of a triangle:

We also learned more about solving algebraic expressions.

For example: 2(5+x)= 2(5) + 2(x)

= 10 + 2x

A common mistake is adding or subtracting 10 by 2x because they are unlike terms.

A new diagram for finding the answer of 2(5+x) is:

Inside the box, the top part is the expression and the bottom part is the answer.

Another example is: 2x(3x^2 + 4x -y)

=6x^3 + 8x^2 - 2xy
