Answer:
Step-by-step explanation: what are the dimensions
Based on the wording of the question, I believe that the answer allows you to pick more than one. However, there still may only be one answer.
Answer:
(5+3y) (x+3)
first of all you bracket by (5x+15)(3xy+9y). and you start fact as follows by 5(x+3y) 3y(x+3)after here you take (5+3y) (x+3)
Ok well the only thing that makes since to me is that the triangle is a Equilateral Triangle, so all the sides are going to be the same. And if the perimeter is 24, then you divide that by 3, and you get 8. And if DEF is the midpoints of triangle ABC, then DEF is an upside down triangle in the triangle ABC. So all the sides of ABC are double whatever DEFs are. And DEFs were 8, so 8 times 2 is 16. And to get the perimeter you add that together 3 times and you get 48. So i'm not sure exactly how you would do this, but i'm pretty sure this is the way. If not i'm sorry i couldn't help. :(

Steps:
1st write out equation
Second write the conjugant and multiply it.
After multiplying you should get,
now after simplifying you should get
