Question

Which expression is equivalent to (-2)(a+6)?

A. -2a+6
B. 2a+12
C. -2a-12
D. -2a+12​

Answer 1

C) -2a-12

Explanation:

you use the distributive property so you multiply -2 by a and 6

(-2)(a) + (-2)(6)

-2a-12

Answer 2

-2a-12

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!
