Question

How can I write an equivalent expression by combining the like terms?-6 + (-2d) + (-4d) + 3d

Answer 1

Answer:

$-6-3d$

Explanation:

Given the below expression;

$-6+(-2d)+(-4d)+3d$

Let's go ahead and clear the parentheses by multiplying the addition sign by the subtraction sign. Note that the product of a positive and a negative sign is a negative sign as seen below;

$\begin{gathered} +\times-=- \\ -\times+=- \end{gathered}$

So the expression will now become;

$-6-2d-4d+3d$

Performing the indicated operations from left to right, we'll have;

$-6-3d$

So the equivalent expression is -6 - 3d
