Jack won 122 pieces of gum playing hoops at the county fair. At school he gave four pieces to every student in his math class. He only has 2 remaining. How many students are in his class?

30 students

Step-by-step explanation:

First, subtract 2 from 122:

122 - 2

= 120

Then, divide this by 4:

120/4

= 30

So, there are 30 students in his class.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
