<em>= 279</em>
Step-by-step explanation:
= + (n - 1)d
d = -
~~~~~~~~~
d = - 17 + 25 = - 9 + 17 = - 1 + 9 = 8
= - 25 + 8(39 - 1) = 279
<em>= 279</em><em> </em>
39,800,000,000 is the correct answer, I believe.
We are technically FOILing this out... with a power of 3.
(x+y)(x+y)(x+y)
So we can first factor out the first two "x+y"s.
, multiplied by the last "x+y".
Coefficients are the number that comes
in front of a variable. In this case, 1 comes in front of
, 3 comes in front of
, 3 comes in front of
, and 1 comes in front of
.
Thus: 1, 3, 3, 1.
