Unclear.  Did you mean


<span>f(x)= [sqrt of x+3]
       --------------------
          (x+8)

or did you mean
                               3
</span><span>f(x)= [sqrt of x] + ----------
                              x+8


I will focus on the first possibility.  The domain of sqrt(x+3) is [-3,infinity).
The domain of    x+3
                          ------- is   "x is not equal to -8."
                            x+8

Then the overall domain would be simply [-3, infinity).

The sides of a right triangle are x, x+21, and x+27. what is the length of the hypotenuse
mina [271]
Answer: 51 uinits

The three numbers are x , x + 21 and x + 27. 
The greatest of the 3 numbers is x + 27, so x + 27 has to be the hypotenuse.

----------------------------------------------
Pythagoras Theorem
----------------------------------------------

a² + b²  = c²

x² + (x+21)² = (x+27)²

x² + x² + 42x + 441 = x² + 54x + 729

x² - 12x -288 = 0

(x - 24)(x + 12) = 0

x = 24 or x = -12 (rejected, length cannot be negative)

----------------------------------------------
Find hypotenuse
----------------------------------------------
 Hypotenuse = x + 27 = 24 + 27 = 51 units

-----------------------------------------------
Answer: 51 units
----------------------------------------------
