Answer:
A. 
Step-by-step explanation:
The question seems to be incomplete. However, we'll make the following assumption.



Pythagoras theorem states that:

Substitute values for Hypothenuse, Opposite and Adjacent.
This gives

or

From the list of given options.
A answers the question
We are given

We can write it as

we can see that 2y is in first two terms
and -8 is in last two terms
so, we can factor it out

now, we can see that x+4 is common in both terms
so, we can factor it out

we can see that
x+4 is one of factor of terms
so, option-B..........Answer
Irrational numbers cannot be represented by a ratio of two integers.
All whole numbers, however, can. This can be done by placing the number over 1. For example 0/1, 34/1, 173635278/1.
A relation is <em>not</em> a function if it has repeated "x" values.
A. (3, _) repeats
B. is a function
C. (5, _) repeats
D. (-4, _) repeats
Two fifths are 4 one fourth is 2 so there are 2 red guppies the fraction that they are red is 2 over 4 the fraction that are not red are 2 over 4 too
