Answer:
60 -047 = 13 in²
Step-by-step explanation:
Paper area: 6 x 10 = 60
15 circles, each circle has diameter: 6 /3 or 10 /5 = 2
each circle area: πr² = 3.14 x 1² = 3.14
15 circles: 3.14 x 15 = 47.1
paper wasted: 60 - 47.1 ≈ 13 in²

Distribute:
=(3)(2y)+(3)(-1)+(2)(3y)+(2)(1)
Combine Like Terms:
=6y+-3+6y+2
=(6y+6y)+(-3+2)
=12y+-1
Answer is: 12y-1
