$4y^2+2=(4y\cdot4y)+2\\
4y^2+2=16y^2+2 \leftarrow \text{not identity}\\\\
4y^2+2=(4y+y)+2\\
4y^2+2=5y+2 \leftarrow \text{not identity}\\\\
4y^2+2=4(y+y)+2\\
4y^2+2=8y+2 \leftarrow \text{not identity}\\\\
4y^2+2=4(y\cdot y)+2\\
4y^2+2=4y^2+2 \leftarrow \text{identity}$

So it's D.

Answer: 1430

Step-by-step explanation: x + y + z = 2680

x = 2z - 100

y = 3z + 80

x + y = 5z - 20

6z - 20 = 2680

z = 450

y = 1430
