5xy-10x
5x are both common, so take that as a factor:
5x(y-2)
And so
5xy-10x = 5x(y-2)
A vertex is the point where two lines meet to form a shape. For example in an angle the vertex would be where the two lines meet.
80 why because in the box are 10 apples each other so if you do this 10*80 thy give you the results
