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

Question

1) –2a + 6
2) 2a + 12
3) –2a – 12
4) –2a + 12

Answer 1

The expression (-2)(a + 6) can be simplified by distributing the -2 to both terms inside the parentheses:

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

This simplifies to:

-2a - 12

Therefore, the expression (-2)(a + 6) is equivalent to -2a - 12. The correct answer is 3) –2a – 12.
