20
Answer:
v=1
Step-by-step explanation:
Based on limited information, it can only be inferred that angle give is either 160 degrees or 20 degrees.

Factor each of the following differences of two squares and write your answer together with solution.

<h3><u>1. x² - 36</u></h3>

Rewrite
. The difference of squares can be factored using the rule:
.

Answer:
There is no answer. I'm sorry but more information is needed in order to find the answer.
Step-by-step explanation:
However, the problem can be written.
It will look like:
3n - 1.
Since the number can be anything, this is not an answerable question because it must equal a number on the right side of the equation.
