THe LCD is x(x^2 - 4)
so multiplying through by this we get:-
2x(x + 2) + 7x =  5(x^2 - 4)
2x^2 + 4x + 7x = 5x^2 - 20
3x^2 - 11x  - 20 = 0
(3x + 4)(x - 5 ) =  0
so x =  5 , -4/3
Its the second choice
        
                    
             
        
        
        
15 points
32/6=5 1/3
if you assume that you only get points after defeating six enemies, you can disregard the 1/3
5*3=15
        
             
        
        
        
10/8 in simplest form:
First, we can start off by finding the GCF of the denominator and the numerator. To do so, we need to list the factors of each of them and find the common ones.
Factors of 10: 1, 2, 5, 10
Factors of 8: 1, 2, 4, 8
We can see that our common factors are 1 and 2, considering that both the numerator and denominator has the same factors (1 and 2). Since we have our common factors, we need to find the greatest. Which is the greatest out of 1 and 2? The GCF is 2 because it is bigger than 1.
Second, divide the numerator and the denominator by the GCF (2).

Third, now we can revise our fraction and turn it into the simplest form. Take the two numbers you just got above us and put them in their numerator and denominator spot. You should get:

Answer:
The rational number equivalent to 3.24 repeating is 321/99
Step-by-step explanation:
To convert the decimal number to a rational number we can state this number and its multiples of 10, trying to find two number with identical decimal parts:
n=3.24242424...
10n=32.4242424....
100n=324.2424242...
Now, 100n and n have the same decimal part, then by subtracting these numbers we obtain:
100n-n=324.24242424...-3.24242424... = 321
99n  = 321
n = 321/99
 
        
             
        
        
        
Answer:
2A + 6C = $60
Step-by-step explanation:
When asked to write and equation or expression, literally. O verte what is in the question to an algebra. The only difference between expression and equation is that equation shows what goes on the other side of the equals sign when expression doesn’t 
Hope this helps
Good Luck
