True, because energy, frequency, and wavelength are all properties of sound, and sound is an electromagnetic wave. The electromagnetic spectrum encompasses a continuous range of frequencies or wavelengths of electromagnetic radiation, ranging from long wavelength, low energy radio waves to short wavelength, high frequency, high energy gamma rays.
I don't understand what one
13 divided by 11.3 is 1.150442477876106. So 15 by 1.150442477876106 and you get 13.03846162772485. Just round it to the nearest tenth and you get 13.0.
Answer:
Step-by-step explanation:
(2x + 3) (-x - 2)
distribute first term, to the second term:
2x(-x) + 2x(-2) + 3(-x) + 3(-2)
multiply:
+ (-4x) + (-3x) + (-6)
combine the like terms:
- 4x - 3x - 6
-7x
- 7x - 6
final answer :
- 7x - 6
hope this helped !!
mark me brainliest :D
120/2=60 (sum of both lengths)
4x+4=60
4x=56
x=14
length=46
width=14
