Answer: -11 degrees Celsius
Step-by-step explanation:
4:00 am = -16 degrees
You know that 4:00am is four hours after midnight and you know that the temperature decreases by 1.75 degrees every hour so during that time it has dropped by:
1.75x4=7 degrees
Because it is -16 at 4:00am, you know it was 7 degrees higher at midnight
-16+7=-11
It was -11 degrees at midnight
Answer:
It should be RGB that's a L
Step-by-step explanation:
Answer: 1
<u>Step-by-step explanation:</u>
a + b = 1
a³ + b³ = (a + b)(a² - ab + b²) <em>formula for a perfect cube</em>
a³ + b³ + 3ab = (a + b)(a² - ab + b²) + 3ab
↓
= 1 (a² - ab + b²) + 3ab
= a² - ab + b² + 3ab
= a² + 2ab + b² <em>this is a perfect square</em>
= (a + b)(a + b)
↓ ↓
= (1) (1)
= 1
