Question

one over three(p + 45)
one over three(p + 5)
3(p + 45)
3(p + 5)

Answer 1

IT IS B!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 2

we know that

the expression " one over
`(3p+15)`" is equivalent to

`(1)/((3p+15))` --------> expression A

and

`3p+15=3(p+5)` --------> expression B

substitute the expression B in the expression A

`(1)/((3p+15))=(1)/(3(p+5))` -----> one over three
`(p + 5)`

therefore

the answer is the option

one over three(p + 5)
