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.

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
