can you work me out in notebook sent in photo so I can understand if you can plz and how to do this question plz

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website

i believe the answer is y=0.25x+-3

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
