Only like terms can be subtracted or added in algebraic expressions.

Algebraic expressions are terms that do not include an equality sign
Because they add onto the expression with every step.
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.

no algebraic expressions do not have equal signs but equations do.
Algebraic expressions are terms that do not include an equality sign
Algebraic expressions are the written relations of or between variables. For example, x2, 1/x, and x + y + z are all algebraic expressions. Algebraic equations are simply algebraic expressions that equate to something. For example, x2 = 4, 1/x = y, and x + y + z = 42 are all algebraic equations. In general, one differentiates algebraic expressions from exponential, trigonometric, hyperbolic, and logarithmic expressions by requiring algebraic expressions to be confined to polynomial expressions. I've added a link regarding polynomials below.

the word algebraic is arabic.
Yes. That is the definition of an algebraic expression.
