Answer:
14. congruent means "THE SAME" so it will be "A" because there all the same letter.
15. D
you can imagine this as a venn diagram. the "or" event would consist of everything in both sides and the middle of the venn diagram because you can choose form either event x <u>or</u> event y.
the "and" event would consist of everything in the middle of the venn diagram because you choice must be a part of both event x <u>and</u> event y.
the complement of an event is just everything that is not included in the event. for example, in a coin flip, the complement of heads is tails. in a dice roll, the complement of {1,2} is {3,4,5,6}
so if you come across these just think "either or" or "both and." and remember that the complement is everything excluding what is listed.
i apologize if this does not help, im not that great at explaining things
It has one solution that is the answer
The value of given expression when m = 3 is 27
<h3><u>Solution:</u></h3>
Given expression is 
We have to evaluate the given expression for m = 3
To find for m is equal to 3, substitute m = 3 in given expression
From given expression,
Plug in m = 3 in above expression
------ eqn 1
We know that,
can be expanded as,
Applying this in eqn 1, we get
Simplify the above expression
Therefore, for m = 3 we get,
Thus value of given expression when m = 3 is found
