The expressions is undefined in the set of the real numbers.
Since the sum of scores must be at least 289:
72+78+70+x ≥ 289
To find the answer to this, you have multiply both expressions by each other. To do this, you have to multiply each term in the first expression by each term in the second expressions. This yields the following: 3x^4-9x^3-3x^2+5x^3-15x^2-5x+10x^2-30x-10. Combing like terms and simplifying gives the final expression: 3x^4 - 4x^3 - 8x^2 - 35x - 10
The sum of the other 2 sides must be greater than 13.
