Are the expressions equivalent? Use j = 3 and j = 8 to determine if they are 76-2)
4-5
No, because when j = 8, the values of the expressions are different
Yes, because when j = 3, the value of both expressions is 7 and when j = 8, the value of both expressions is 42
O Yes, because when j = 3, the value of both expressions is 7
O Yes, because when j = 8, the values of the expressions are different
