Iwill give brainliest to whoever is correct.

the domain is the numbers you can use for x

x is how many papers you can buy

you can't buy negative papers

but the store only has 5 papers so the answer is all inegers from 1 to 5 including 1 and 5

integes are like -3,-2,-1,0,,2,3,4, but since we have 1 to 5 we have 1,2,3,4,5

it isn't all real numbers from 1 to 5 because you can't buy 3.141592 reams of paper

answer is first one

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
