Answer:

the three red tiles in the model represents -3x

Explanation:

From the given diagram, the three red tiles have -x, -x and -x

To find what 3 red tiles represents , we need to add all the three red tiles

Red tiles represents -x + -x + -x

Combine all the terms to add it

All terms are like terms. -x means -1x


-1x+(-1x_+(-1x) = -1x-1x-1x= -3x

So , the three red tiles in the model represents -3x
