Answer:

Step-by-step explanation:

hello :

let : f(x) this denominator :

12/x(x+4) = f(x)/x(x+4)(x-9)

f(x) =12x(x+4)(x-9)/x(x+4)

if : x(x+4)(x-9)≠0    simpify by : x(x+4)

f(x) = 12(x-9)

If n represents a number then write an expression for two less than one fourth of n
Ne4ueva [31]

Answer:  \frac{1}{4}n-2

This is the same as \frac{n}{4} - 2 and it is also equivalent to 0.25n-2

=====================================================

Explanation:

n is some placeholder for a number

one fourth of that number is \frac{1}{4}n which is the same as \frac{n}{4} or 0.25n since 1/4 = 0.25

From here, we subtract off 2 to get \frac{1}{4}n-2 as one possible final answer.
