Asound wave travels through iron at a rate of 5120\,\dfrac{\text{m}}{\text{s}}512 0 s m 5120, start fraction, start text, m, end text, divided by, start text, s, end text, end fraction. at what rate does the sound wave travel in \dfrac{\text{km}}{\text{h}} h km start fraction, start text, k, m, end text, divided by, start text, h, end text, end fraction? \dfrac{\text{km}}{\text{h}} h km

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

yes

step-by-step explanation:

just sum

10 + 10 = 20

150
