If

is true, then

is false, which in turn means

is true.
If

is false, then

is true, and so

is false.
So, because

in both cases, the statement is a tautology (always true).
If you were to put this in a table, you would have one column each for

. In the first column (

) you can think of

as an independent variable that can only take two values, true and false. In the next column (

), you would negate the value in the previous column. And so on.
It should roughly look like this:
p ... ~p ... ~(~p)
T ... F ... T
F ... T ... F

Answer:
B. 12n=78
Step-by-step explanation:
Answer:
p = -40
Step-by-step explanation:
<u>Step 1: Distribute
</u>
8(61 + p) = 168
(8 * 61) + (8 * p) = 168
488 + 8p = 168
<u>Step 2: Subtract 488 from both sides
</u>
488 + 8p - 488 = 168 - 488
8p = -320
<u>Step 3: Divide both sides by 8
</u>
8p / 8 = -320 / 8
<em>p = -40
</em>
Answer: p = -40
