400x6=2400 This is how a find a product
-13 and -14
They both are consecutive negative integers that multiply to 182.
Twice the difference of a number and 3 is at most 27
2*(n-3) <=27
to solve
distribute
2n -6 <=27
add 6 to each side
2n <=33
divide by 2
n <=33/2
n<= 16 1/2
It looks like the first 3 are because they all are blank x2.5 but the last one would be 8x2.5=20..
