• i understand this but the vidio did not help me with my question
• why would you divide 8.50 to find the margin
• because you would have half on one side and half on the other if the Margin on the left was 8.50 then the other side would equal it
• The quiz for this section is out of its tree compared to the examples given in these videos 🙄
• What does centered mean ?
• It means to put a object in the center of a paper
• why would you divide 8.50 to find the margin
• Just like how Sal Khan states at , if the figure is centered, you must divide in order to make sure the margin fits both sides.
• this is a very stupid place to text each other!
