Answer:
2 pounds
Step-by-step explanation:
1 pound = 1/2 hour (30 minutes)
x pound(s) = 1 hour (60 minutes)
Equation:
1 pound · (2) = 1/2 hour · (2)
2 = 1 hour
The answer is 9x^2+36x+36
You can distribute the -3 to the x and the 2 to get -3x-6 and then because it’s squared it gets multiplied by itself so (-3x-6) times(-3x-6) which gives you the answer of 9x^2+36x+36
2.48 > 2.471 > 2.463
5.723 < 5.724 < 5.725
7.64 < 7.65 < 7.68
