Conversion factors:
2 pints = 1 quart
4 quarts = 1 gallon
60 minutes = 1 hour
15 pints/minute x 60 minutes/hour x 1 quart/2 pints x 1 gallon/4 quarts = 112.5 gallons/hour
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
Step-by-step explanation:
f(x) = 4x + 5, g(x) = 9x − 4
(f-g)(x) = f(x) -g(x)
=4x+5-9x+4
=-5x+9
=9-5x
