Answer:
There are 6 stores that have more that 38 pairs of glasses
Step-by-step explanation:
There are 6 stores that have more that 38 pairs of glasses
41,42,43,43,45,47
If your denominators are
x² + 4x - 12 = (x +6)(x -2)
and
x² + 7x + 6 = (x +6)(x +1)
Then the common denominator is the product of unique factors:
(x +6)(x +1)(x -2)
