Answer:
Therefore 12.5 centimeters on the map represents an actual distance of 5 kilometers.
Step-by-step explanation:
Given:
The scale map shows that
5 centimeters =2 kilometers.
To Find:
What number of centimeters on the map represents an actual distance of 5 kilometers?
Solution:
Let 'x' cm be on the map to represent 5 kilometer.
Given:
5 centimeters = 2 kilometers.
Therefore,
x cm = 5 kilometer
Soon Equality of proportion we get
Therefore 12.5 centimeters on the map represents an actual distance of 5 kilometers.
The question is incomplete. Here is teh complete question.

Answer and Step-by-step explanation: The definition of polynomial is "poly" meaning many and Nominal, which means terms. So, <u>Polynomial</u> is an expression of constants, variables, exponents that are combined using mathematical operators: addition, subtraction, multiplication and division.
However, there are exceptions:
- Polynomial don't have negative exponent;
- Polynomial cannot be divided by a variable;
- Variable cannot be inside a radical;
The <u>degree</u> <u>of</u> <u>a</u> <u>polynomial</u> is the highest exponent of that variable. For example for polynomial , the degree is 5.
Polynomials have 3 different types:
- monomial: only has one term;
- binomial: has 2 terms;
- trinomial: has 3 terms;
Now, analysing each expression given by the alternatives above:
1. It is a polynomial of degree 3 and trinomial.
2. It is a polynomial of degree 2 and trinomial.
3. Yes, its a polynomial of degree 2 and monomial.
4. It is not a polynomial because it is divided by a variable.
5. A polynomial of degree 5 and it's a binomial.
6. It is not a polynomial due to the exponent being negative.
