For this case we have the following expression:

We apply distributive property, which by definition establishes that:

So:

Answer:

1 base. The triangular pyramid has 1 base, and that is the square at the bottom. Hope this helps.
Answer: 3(n-2) =3n-6
Step-by-step explanation: There all separate groupings
14^(7x) = 17^(-8-x)
Take the log of both sides:
7x*log 14 = -(8+x)*log 17, or 7x^log 14 = -8*log 17 - x*log 17.
Grouping the x terms, we get x(7*log 14 + log 17)= -8*log 17
Then:
-8*log 17
x= -------------------------- (answer)
7*log 14 + log 17
Just divide 105 by 20
this gives you 5 5/20
this can then be reduced to 5 1/4
answer: 5 1/4
