Answer:
<em>summation of five times negative three to the power of n from n equals zero to infinity</em>
Step-by-step explanation:
<u>Summation Notation
</u>
It represents the sum of a finite or infinite number of terms. Let's analyze the terms of the given succession:
5-15+45-135+...
If we take 5 as a common factor, we have
5(1-3+9-27+...)
The parentheses contain the alternate sum/subtraction of powers of 3. The odd terms are positive, the even terms are negative, thus the exponent must be n starting from 0 or n-1 starting from 1
The summation is then represented by
This corresponds with the option:
<u>summation of five times negative three to the power of n from n equals zero to infinity</u>

Answer:
Top right (one what has 16cm^2 and 9cm^2)
Step-by-step explanation:
The one in the top right and even though I cannot see what the area is of the biggest square, I can tell what it should be the two smaller squares combined
Hope this helps :)
The best thing to do is figure out what we can deduce to isolate what we can't deduce.
The first answer is true because angles 1 and 8 are congruent by the Alternate Exterior Angles Theorem, which states that if two lines are congruent, it's alternate exterior angles are congruent.
The second answer is true by the Same-Side Interior Angles Theorem, which states that angles created by a transversal that are both in the interior of the transversal are congruent.
The third choice is incorrect, and we know this is true because the previous theorem we used (Same Side Interior Angles) is shown again, but with different angles. Therefore, Choice C is incorrect, and therefore your answer.
(As a side note, Choice D is correct, but a short proof must be written to prove this, as it is not defined by a single postulate or theorem).
