Answer:
13
Step-by-step explanation:
We need to use the Pythagorean Theorem to solve this problem:
, where a and b are the legs of the right triangle and c is the hypotenuse
In this case, we already know b (b = 84) and c (c = 85), so we need to solve for a:

Thus, a = y = 13.
Answer:
The answer is the option D

Step-by-step explanation:
we know that
The inequality

has two solutions
<u>First solution</u>

The solution is the interval-------> (2,∞)
All real numbers greater than 
<u>Second solution</u>
------>
-
The solution is the interval-------> (-∞,-2)
All real numbers less than 
using a graphing tool
see the attached figure
Using the FOIL Method (First, Outer, Inner, Last) of multiplying binomials, C would be formed by the last numbers multiplied, or the "last" portion of "FOIL."
Thus, multiplying P and Q would give you C, and the answer is A.
