I am going to go with the assumption that your equation is

. If there is only one solution, then the equation must be a perfect square. So square

to solve for the equation in the similar form that is given.

. So the variables match up perfectly in the equation, meaning that the value of m is 6, letter choice C.
4p+5=32 or 7 packages
I got this because there are 4 bracelets in one package and she doesn't know how many packages she needs so we put p for packages next to the 4 and you already have 5 so you add the 5 to it, all of that should come out to 32. If the equation wasn't what you were looking for you subtract 5 from 32 and get 27, then you divide 4 by 27 and you get 6.75, then you round it up and you get 7. The number of packages she needs is 7.
