d = 2 and d = 6
Work Step by Step
Divisibility Rules state that a number is divisible by 4 if its last two digits form a number that is divisible by 4. In the number 752,67d, we can substitute the numbers 0 through 9 for d. We use the last two digits, 7d, with d being unknown. Once we check each substitution, we find that only 72 and 76 are divisible by 4; therefore, d can only take on the values of 2 and 6.
