If y is 12 less than the product of a and b, then which of the following is an expression for y in terms of a and b ? 12 − (a + b) (a + b) − 12 12 − ab a/b − 12 ab − 12

ab -12 

Given that y is 12 less than the product of a and b. 

The product of a and b is the multiplication of a and b:
a x b = ab

12 less than the product will mean that we need to take away 12 from ab, so 
y = ab - 12


ab - 12

Ithink is a. true, but not sure

There is no association.
