Question

Which expression is equivalent to one over 3p + 15?

Answer 1

we know that

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

$\frac{1}{(3p+15)}$ --------> expression A

and

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

substitute the expression B in the expression A

$\frac{1}{(3p+15)}=\frac{1}{3(p+5)}$ -----> one over three$(p + 5)$

therefore

the answer is the option

one over three(p + 5)
