If you have a expression that goes;
2x + 5x etc etc
Simplifying the like terms is
7x
2x and 5x are like terms, but 2y and 2x are not. The variable needs to be the same.

It means to rewrite the expression so that it is in its simplest form. You can do this by combining like terms. For example: The equation 2x + 3x = 5 can be simplified to 5x = 5 by combining the "x's".
It is an expression of algebraic terms with no equality sign
A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. An algebraic expression is an expression with a variable in it, and a polynomial is an expression with multiple terms with variables in it.
An algebraic expression is a collection of terms but does not include an equality sign.
To add and subtract algebraic expressions the simple rule of like terms applies. In your homework that asks for the expression represents the perimeter in units of this trapezoid you will need to find the like terms and simplify.
