Answer:


-6-3d

Step-by-step 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} +*-=- \\ -*+=- \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
