So, if you are trying to convert lightyears to miles, you'll do so with this formula:
mi= (ly)* 5.9e^12, or 59,000,000,000,000. so it would be:
miles=(4.24)(5.9e^12)= roughly 2.5e^13 so Proxima Centauri is 250,000,000,000,000 miles from the Sun
To convert miles to lightyears, you'll just switch them around:
lightyears= (3.6e^6) / (5.9e^12)
Mercury is roughly 0.000006123880 lightyears from the Sun
Answer:
c
Step-by-step explanation:
252 = 7 *36
36 = 6 *6 = 6²
a² -b² = (a + b)(a - b)
7h² - 252k² = 7(h² - 36k²)
= 7(h² - [6k]² )
= 7(h +6k)(h - 6k)
I'm using PEDMAS.
Multiplication first.
2 • 4 = 8
Subtraction.
20 - 4 = 16
16 + 8 = 24
