Answer:  No; they are not equivalent.

_____________

Step-by-step explanation:

_____________

<u>Note</u>: The ratio:  " 1:2 " ;  can be written as:  " \frac{1}{2} " ;

         The ratio:  " 5:18 " ; can be written as: " \frac{5}{18} " .

  → " \frac{1}{2}  \neq  \frac{5}{18} " ;

_____________

 → " \frac{1}{2} = \frac{(1*9)}{(2*9)} = \frac{9}{18} " ;

                   → " \frac{9}{18} \neq \frac{5}{18} " ;

_____________

 → " \frac{1}{2} = \frac{(1*5)}{(2*5)} = \frac{5}{10} " ;

                   → " \frac{5}{10} \neq \frac{5}{18} " ;

_____________

 → " \frac{5}{18} = \frac{(5/9)}{(18/9)} = \frac{0.5555555555...}{2} " ;

_____________

                   → " \frac{0.555555555...}{2} \neq \frac{1}{2} " ;

_____________

 → " \frac{5}{18} = \frac{(5/5)}{(18/5)} =\frac{1}{(3.6)} " ;

                   → " \frac{1}{(3.6)} \neq \frac{1}{2} " .

_____________

What is the simplest form of x^2+5X-36/x^2-16<br> X+9/X+4<br> 9/4<br> X+9/X-4<br> -9/4
Digiron [165]

Answer:

\frac{ {x}  + 9}{x - 4}

Step-by-step explanation:

\frac{ {x}^{2}  + 5x - 36}{ {x}^{2}  - 16}  \\  \\  = \frac{ {x}^{2}  + 9x  - 4x- 36}{ {x}^{2}  -  {(4)}^{2} } \\  \\  = \frac{ x({x}  + 9)  - 4(x + 9)}{ (x + 4)(x - 4) }  \\  \\  = \frac{ ({x}  + 9) \cancel{(x  - 4)}}{  \cancel{(x + 4)}(x - 4) } \\  \\  = \frac{ {x}  + 9}{x - 4}
