Answer: The answer is d

Step-by-step explanation: This is because a, would have the answer as -63 b would make the answer be -490, and c would have below 63 because -7 x -9 = 63 but if x is below -9 then it would be to low. Lastly for D since a negative times a negative is a positive then you can ignore the negative symbols and just substitute x for 70 and -7 for 7 then multiply. 7 x 70 = 490 which matches the inequality because it is more than 63.
