The answer to you’re question is 5 1/2 multiplied by 5 1/3. I submitted a photo showing how to put the answer.
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.
That’s how you solve complex numbers.
Answer:
Im certain The answer is -4
Let me know if im wrong :)
Answer:

Step-by-step explanation:
Let x be the distance from the foot of the ladder to the base of the building.
We have a right triangle, so we can use Pythagoras' Theorem.
