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
