reduce the negations for all of the following:
3) ~ (a < --> b)
4) (~a & ~b) & (~c v ~d)
5) a --> (b v ~c)
6) [a --> (b --> ~c)] --> [(~d --> ~e) --> f]
7) ~a v ~b
8) ~(a v b)
9) [~~a v (~b & c)] v (~~d --> ~~~e)
10) ~(a < --> b)

126 maybe. sorry

they would have to work 32 hours.

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second

step-by-step explanation:

4y - 6 + y^2 - 9 = y^2 + 4y - 15

y^2 term

total of 3 terms when simplified
