V1 = V2 + 18

V1 =

3 \times 6 \times x

V2 =

\frac{4 \times 7 \times x}{2}

Do the maths...

3 \times 6 \times x =  \frac{4 \times 7 \times x}{2}  + 18

18x = 14x + 18

4x = 18

x = 4.5

So

The volume of the rectangular prism is 81 cubic feet.

The volume of the triangular prism is 63 cubic feet.

What is the correct truth table for ~p^~q?
Kisachek [45]
This symbol - ~ - is the "not" symbol, which means the opposite.  So I think were given values for p and q?  If so, you just reverse the p values to get ~p (true becomes false or 1 becomes 0 or yes becomes no).  
This symbol ^ is the "and" symbol.  That means that you need to figure out if both ~p and ~q are true.  If so, your result is true (or 1 or yes, depending on which the problem uses).  Otherwise, your result is false (or 0 or no) for each corresponding ~p and ~q value.
