Answer:
(3) 2(3x - 5)(3x + 5)
Step-by-step explanation:

Items bought in total:
4 brothers X two hot dogs and one bag of chips=
4X3=
12.
Hot dogs- x, chips- y.
4y + 8x= $18.20
Chips= $1.25 each so
4($1.25) + 8x= $18.20
5 + 8x= $18.20
8x= $18.20-5
8x= $13.20
x= $13.20/8 [13.20 divided by 8]
x= $1.65
This means that one hot dog= $1.65.
If you’re unsure what to write as the answer I’d suggest that you put all the working out down in your copy/notes.
