Given the expression 42 + 96, which value of a could NOT be used to create an equivalent expression in the form a(b + c) where a is a common factor of 42 and 96? A) 2 B) 3 C) 6 D) 7
2, 3, and 6 are common factors of 42 and 96. 7 is not. If a, b, and c are to be integers, the value of "a" must be a common factor of 42 and 96. It cannot be 7.
