4.5 x 10^6 = 4,500,000
2.1 x 10^8 = 210,000,000
Therefore, 4.5 x 10^6 < 2.1 x 10^8

Step-by-step explanation:
Answer: Earth: radius = 6378 kilometer, diameter = 12756 kilometers.
Answer:
(2 x + 3) (2 x + 9)
Step-by-step explanation:
Factor the following:
4 x^2 + 24 x + 27
Factor the quadratic 4 x^2 + 24 x + 27. The coefficient of x^2 is 4 and the constant term is 27. The product of 4 and 27 is 108. The factors of 108 which sum to 24 are 6 and 18. So 4 x^2 + 24 x + 27 = 4 x^2 + 18 x + 6 x + 27 = 9 (2 x + 3) + 2 x (2 x + 3):
9 (2 x + 3) + 2 x (2 x + 3)
Factor 2 x + 3 from 9 (2 x + 3) + 2 x (2 x + 3):
Answer: (2 x + 3) (2 x + 9)
6/10 and 5/10
The common denominator is 10
