Answer:
21 ÷ 1.4
Step-by-step explanation:
Sanya noticed that the temperature was falling at a steady rate of 1.4 degrees every hour.
The temperature had fallen 21 degrees, so it passed
hours after she had first checked the thermometer.
She had first checked the temperature at 3 p.m.
Dividing two binomials will not always result in a polynomial. For instance, divide (x+2) over (x+3) and we won't get a polynomial. The result is known to be a rational expression but not a polynomial. So that's why division is not closed for polynomials.
Contrast that with addition, subtraction and multiplication. For any of those operations taking two polynomials and adding them, subtracting them, or multiplying them will lead to another polynomial. That's why these operations are closed for polynomials.
