2. It is an expression. Reason being the absence of the equal sign.
3. It is again an expression. There is no equal sign :)
4. This is an equation. Two expressions are separated by the equal sign.
5. Expression. I hope by now you know what made this only an expression.
6. It is an equation. You're smart, you already know the reason :)
B.
You're smart, I know you know this. You're probably just lazy. But an equation is any two expressions connected by an equal sign. Just write anything you think of, just make sure there are variables present. But anyway, here:
1. 5x + 9 = 37
2. 2y + 5 = 12
3. 18 - 16z = 13z
4. 28x + 13 = 19x
5. 2y + 8 = -15
For the algebraic expression, write anything with any variables connected by mathematical operations.
