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!

Answer:
It would be a right triangle
Step-by-step explanation: I drew it out
We rewrite the expression:
((m-4) / (m + 4)) * (1 / (m + 2))
Then we do the multiplication of fractions:
((m-4) / (m + 4) (m + 2))
answer:
An equivalent expression is:
((m-4) / (m + 4) (m + 2))
option 1
Pick me as the brainliest answe please
1. Let A(a,b) be a point in the coordinate axis. The reflection of A with respect to the x-axis is the point A'(a, -b).
2. So the reflection of C(6, 4) is C'(6, -4)
3. Remark, a picture is always helpful when dealing with reflections.
