maria [59]

Answer:

r > -69

Step-by-step explanation:

13 - r < 82

subtract 13 from both sides

13 - r - 13 < 82 - 13

- r < 69

to flip the inequality sign, multiply both side by -1 to make r positive:

- r (-1) < 69 (-1)

r > -69

Simplify x^2-9 over x^2-3x

Alla [95]

Answer:

$\frac{x+3}{x}$ or x+3/x

Step-by-step explanation:

Using D.O.T.S (difference of two squares) formula :

$a^{2} -b^{2} = (a+b)(a-b)$

$x^{2} -9= (x+3)(x-3)$

Factorise the second bit:

$x^{2} -3x = x(x-3)$

Now write out this fraction:

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

Now we can cancel out repeated terms (x-3):

$\frac{(x+3)}{x}$
This is our final answer:

$\frac{x+3}{x}$
