Simplify the rational expressions. State any excluded values. X^2-4/2-x
tatiyna

Answer:

-x-2;  x\neq2

Step-by-step explanation:

\frac{x^2-4}{2-x}-->

\frac{(x-2)(x+2)}{(2-x)} -->

-(x+2); x CAN'T equal 2, because the denominator of the original fraction would be 0, which would make the term undefined.

Can somebody help me with this?
Juli2301 [7.4K]

Answer:

E) 1/2

Step-by-step explanation:

This is no ordinary problem. It actually requires you to solve two different problems in order to figure out the correct answer.

First, we must figure out what the hypotenuse of the triangle is. We have the two small sides (5 and 12), but don't have the larger side. To find this, we must use the Pythagorean theorem: a^{2} + b^2 =c^2

Let's plug in our a and b values

5^2 + 12^2 = C^2

Simplify

144 + 25 = c^2

169 = c^2

Square both sides

c = 13

But sadly, we aren't done yet. Now we know the length of the whole hypotenuse side. Time to figure out what X is by a simple equation.

12x + 14x = 13

Simplify

26x = 13

Divide by 26

Answer is 1/2
