Answer: Wavelength is the distance between sound waves while frequency is the number of times in which the sound wave occurs.
Step-by-step explanation:
The Answer should be 7.5
If you would like me to elaborate, let me know
It would be 123,456,789 (if not counting decimals)
decimals would be like 0.123456789
l = 2w + 4
l * w = 48
We can substitute l with its value:
2w + 4 * w = 48
2w^2 + 4w - 48 = 0
2(w^2 + 2w - 24) = 0
2(w+6)(w-4) = 0
w = {4, -6}
