Someone give me the answer

We want to begin with nine, which gives us as follows:

9

Then, we want to subtract:

9 -

And we are subtracting x:

9 - x

The expression is 9 - x for the steps in the image given.

Hope this helps!! :)

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
