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

  D)  7

Step-by-step explanation:

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.

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
