Answer: Jamar is correct
Step-by-step explanation:
Integer is a number that is a whole number and can either be positive or negative but it can't be a fraction or decimal. e.g 4, -2, 6, -23 etc.
A whole numbers are zero and other natural numbers such as 1, 4, 23. Negative numbers are not part of whole numbers.
From the statement made in the question, Sophia is wrong while Jamar is correct. The numbers aren't all whole numbers because some are negative.
So to find x, you have to add both A and B which is 38. Since AuB (excluding the overlap) is 29, subtract 38 from 29 and you get 9 for x.
