Answer:
5 - 3c + 21 --> 3 terms
Step-by-step explanation:
Step 1: A term is a number by it self or a number & variable. Ex: 5 + 6c.<u> </u><u><em>5</em></u> would be one term, <u><em>6c</em></u> would be the other.
Step 2: Now, let's look at 5 - 3c + 21.
Step 3: 5 is a term by it self. Since there is no variable, it's just 5.
-3c is a term by itself. And, there is a variable, so it's -3c.
+21 is a term by itself. Since there is no variable, it's just +21.
Note: You must carry the sign with it. For Ex: 5 - 3x + 21
If you were given a question, "What is the third term of this equation?" you would write, "+21". You will always need to carry the sign with the number.
