Question

r+10/r2-100

Answer 1

1/ (r-10)

Answer 2

how did u get the answer

Answer 3

i do not get fractions

Answer 4

the denominator is a difference of squares...so it factors to (r+10)(r-10)

so it can be written as (r+10) / (r+10)(r-10)

the (r+10)'s cancel...so your left with 1 in the numerator and (r-10) in the denominator..thus 1/(r-10)

Answer 5

these aren't fractions

Answer 6

\[\frac{r+10}{x^2-10}=\frac{x+10}{(x+10)(x-10)}=\frac{1}{x-10}\]

Answer 7

sorry r not x

Answer 8

\[\frac{r+10}{r^2-100}=\frac{r+10}{(r+10)(r-10)}=\frac{1}{r-10}\]
