Which expression is equivalent to (-2)(a+6)???
a. -2a+6
b. 2a+12
c. -2a-12
d.-2a+12
-2 * a = -2a
-2 * 6 = -12
-2(a+6) = -2a - 12.
he is right thanks henry2,
To find the expression that is equivalent to (-2)(a + 6), we can simplify the expression by distributing the -2 to both terms inside the parentheses.
Here's the step-by-step explanation:
(-2)(a + 6)
= -2 * a + (-2) * 6 (multiply -2 with each term inside the parentheses)
= -2a - 12 (simplify the multiplication)
So, the equivalent expression is -2a - 12.
In this case, the correct option is (c) -2a - 12.
