The two numbers are (5+ √(129))/2 and (5-√(129))/2.

(5+ √(129))/2+ (5-√(129))/2= 5
(5+ √(129))/2* (5-√(129))/2= -26

Hope this helps~

What is the sum? StartFraction 3 Over x squared minus 9 EndFraction + StartFraction 5 Over x + 3 EndFraction
Karolina [17]

Answer:

The answer is:

\frac{5 x - 12}{(x + 3)(x - 3)}

Step-by-step explanation:

\frac{3}{x ^{2}  - 9}  +  \frac{5}{x + 3}

First, we have to make the denorminator same by multiplying:

\frac{3}{(x + 3)(x - 3)}  +  \frac{5}{x + 3}

\frac{3}{(x + 3)(x - 3)}  +  \frac{5(x - 3)}{(x + 3)(x - 3)}

Then, we can add up everything together:

\frac{3 + 5x - 15}{(x + 3(x - 3)}

\frac{5x - 12}{(x + 3)(x - 3)}

(Sorry if being messy)

The questions says that we need to find bat.
In order to find bat, it is assumed that it is multiplication 

So that is bat = b * a  * t

Amanda bought 4 shirts and 9 skirts for $168.75. On another day she bought 3 shirts and 12 skirts for $172.50. How much did she
Karolina [17]

Answer:shirt = $22.5

skirt= $8.75

Step-by-step explanation:

Let shirt be x and skirt be y

4x + 9y = 168.75--------1

3x + 12y = 172.5---------2

Using elimination method

Multiply eqn 1 by 3 and eqn 2 by 4

12x + 27y= 506.25

12x + 48y = 690

Subtracting

-21y = -183.75

y = $8.75

Put in eqn 1

4x + 9×8.75 = 168.75

4x = 168.75 - 78.75

4x = 90

x = $22.5
