Final answer:
The expression 35/d - 17/d simplifies to (35 - 17)/d, which equals 18/d with the condition that d is not equal to zero.
Step-by-step explanation:
To simplify the expression 35/d - 17/d, since both terms have the same denominator, d, you can combine them by subtracting the numerators. The simplified expression is (35 - 17)/d, which equals 18/d. Remember, d ≠ 0 means that d cannot equal zero, as division by zero is undefined in mathematics.
