In mathematics, a set A is a subset of a set B, or equivalently B is a superset of A, if A is "contained" inside B. I belive the correct answer from the choices listed above is the second option. It is the set {5, 6, 7} that is a subset of <span> {1, 3, 5, 7, 9}. Hope this answers the question</span>

b = -3 * 3
multiply 3 * 3 so it can = 9
Answer: b = -9
