    The four X's are supposed to be spaced out between the lines. You're supposed to match each model with it's expression. The regular line represents the variable

    the x btween lines matches with 4x.. as u see there are x's and red line is above all of them so u have to add all 4 of them.. x+x+x+x = 4x
