The original area of a face would be a^2. Now that you added b to the edge, the new area of each face would be (a+b)^2. To find how much the are increased, subtract a^2 from (a+b)^2.
So the answer is b(2a+b)
A I think Sorry if it’s wrong
Because if X is ten then the equation is complete

Hope that helpful !
Answer: The equation of this graph can be written in slope intercept form which is what I am assuming you want. If you do not want that form you can convert to any other form that you so desire. The slope intercept equation for this graph would be y = -1x - 2. The -1 is the slope of the line and the -2 is the y intercept.
