Question

Which expression is equivalent to x-5/(x-5)(x-4) A)1/x-4 B)x-4 C)1/-9x-4 D)-9x-4

Answer 1

Answer:

Option A - $\frac{1}{(x-4)}$

Step-by-step explanation:

Given : Expression $\frac{x-5}{(x-4)(x-5)}$

To find : Which expression is equivalent to given expression

Solution :

Step - 1 : Write the expression

$=\frac{x-5}{(x-4)(x-5)}$

Step -2 : Factor (x-5) cancel out from numerator and denominator

$=\frac{1}{(x-4)}$

Therefore, Option A is correct.

$\frac{x-5}{(x-4)(x-5)}=\frac{1}{x-4}$

Answer 2

X-5/(x-5)(x-4)
=1/（x-4）

so A
