Subtract (5y3 + 6y + 3y4) from (4y4 - 8y3). with step by step work***

  4y⁴ - 8y³ - (5y³ + 6y + 3y⁴)

= 4y⁴ - 8y³ - 5y³ - 6y - 3y⁴

= (4y⁴  - 3y⁴) + (- 8y³ - 5y³) - 6y

= y⁴ - 13y³ - 6y

 y⁴ - 13y³ - 6y

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
