Answer:
a rational number is an expression in which the numerator and denominator are polynomials. this is useful to know because often polynomials can be factorized. besides, if there is a variable in the denominator, there will be one or more restrictions.
example: (4x²-25)(2x+5) is simplified to 2x-5 with restrictions x≠-5/2
Answer:
3.9x + 0.8y
Step-by-step explanation:
Simplify:
- 4x - 5.2y + 6y +7.9x - 8x
- 4x + 7.9x - 8x - 5.2y + 6y
- 11.9x - 8x + 0.8y
- 3.9x + 0.8y
