She needs 23 boxes because 22.25 boxes doesn’t make sense.
The answer is 23 boxes not 22
the zeros and the x-intercepts are the same with different names
x -intercepts are (- 7, 0 ) and (2, 0 )
if x = a is a zero then (x - a ) is a factor
thus (x + 7 ) and (x - 2 ) are the factors
2 divided by 2 is one (1)
