Answer: Second option.
Step-by-step explanation:
Let be "e" the number of easy puzzles Tina solved and "h" the number of hard puzzles Tina solved.
Set up a system of equations:
You can use the Eliminationn Method to solve this system of equations:
- Multiply the first equation by -30.
- Add the equations.
- Solve for "h".
Therefore, through this proccedure, you get:
To qualify as a polynomial, the expression in question:
* Consists of one or more terms
* Variables are only with positive whole exponents
* No variables in the denominator of any term (the coefficients however, can be fractions.)
In that case the answer is most likely:
* Consists of one or more terms
* Variables are only with positive whole exponents
* No variables in the denominator of any term (the coefficients however, can be fractions.)
In that case the answer is most likely:
