What is s=3(w-s) solve for s?
go into detail about the steps.

Step-by-step explanation:

Given:

To solve for , we have to isolate it on one side of the equal sign. Let's start by getting rid of that coefficient of from . To do that, divide by

To isolate all we need to do is put it on one side of the equal sign. Let's subtract from both sides to get all by itself.

We aren't done yet, we solved for not . All we need to do is divide everything by to cancel out the negative sign on . What that basically does is change ALL the signs.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
