Answer:
The given expression is:
m/T = 0(9x-17) / (T(4x + 28)S R)
Since the numerator is multiplied by 0, the entire expression becomes 0, regardless of the value of the denominator. Division by 0 is undefined in mathematics, as it is not a valid operation. Therefore, the result of m/T in this case is undefined.
You can double check urself ;D
