Answer:
The sound takes time to go to a point and reflect back to your position.
It means the sound went twice a distance.
=> Suppose it takes about 0.5 seconds to hear the echo, the canyon wall would be [750 x (0.5/3600)]/2 = 0.052 miles
=> Suppose it takes about n seconds to hear the echo, the canyon wall would be [750 x (n/3600)]/2 miles
Hope this helps!

If we combine these two things then we get theproduct property of radicals<span> and the quotient </span>property of radicals. These twoproperties<span> tell us that the square root of a </span>product<span> equals the </span>product<span> of the square roots of the factors
</span>
This is an example of the
difference of squares.

So to find the product of <span>(9y</span>²<span> – 4x)(9y</span>²<span> + 4x), we use the formula for the difference of squares.
