Answer 2

Answer:

-2a-12

Step-by-step explanation:

From Distributive Property, states that:

$\displaystyle \large{x(b + c) =x b + xc}$

Compare the number/term, we can say that:

• x = -2
• b = a
• c = 6

Substiture these values in.

$\displaystyle \large{ - 2(a + 6) = - 2 a - 2(6)} \\ \displaystyle \large{ - 2(a + 6) = - 2 a -12}$

And we're done!
