Answer:
The expression of (5)(x+3)(y+3) is a binomial
Multiply out the bracket so
-27 + 36w - 8w
Then collect the terms so
-27 + 28w
Answer = - 27 + 28w

For the sequence 2, 6, 18, 54, ..., the explicit formula is: an = a1 ! rn"1 = 2 ! 3n"1 , and the recursive formula is: a1 = 2, an+1 = an ! 3 . In each case, successively replacing n by 1, 2, 3, ... will yield the terms of the sequence. See the examples below.
