Distribute sum groups
x(x^2 + 4x - 2) - 5(x^2 + 4x - 2)
Distribute
x^3 + 4x^2 - 2x - 5(x^2 + 4x - 2)
Distribute
x^3 + 4x^2 - 2x - (5x^2 + 20x - 10)
Simplify brackets
x^3 + 4x^2 - 2x - 5x^2 - 20x + 10
Collect like terms
x^3 + (4x^2 - 5x^2) + (-2x - 20x) + 10
Simplify
<u>x^3 - x^2 - 22x + 10</u>
Answer:
It would take more than 16 weeks to drop below freezing.
Step-by-step explanation:
The temperature is dropping from 96°F to 32°F at a rate of 4°F per week, where 32°F is the freezing point.
Hence, 32 = 96 - 4w { Where w week is required to reach 32°F }
⇒ 4w = 64
⇒ w = 16
Therefore, it would take more than 16 weeks to drop below freezing. ( Answer )
