See Step by step explanation

Step-by-step explanation:

(g+f)(x) = g(x) + f(x) = 7x-1\\(g'f)(x) = g(x)f(x) = (3x-1)(4x) = 12x^{2}-4x\\(g-f)(-2) = -(-2)-1 = 1

PLEASE HELP WILL MARK BRAINLIEST The frequency f​ (in waves per​ second) and the wavelength w​ (in meters) of a sound traveling
marshall27 [118]

You gave us the speed and the frequency, and you need the wavelength.

You were also nice enough to remind us that (fqy)x(lng) = speed.

So . . . F x W = 343 m/s

Divide each side by F :

W = (343 m/s) / F

W = (343 m/s) / (240 / s)

W = (343/240) m

<em>W = 1.429 meters</em>
