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

So it's D.

What is the percent of 14 out of 20? If someone could explain how I would find the percentage that would be great. :)

14/20 = 0.7....multiply by 100 to get ur percent = 70%
so 14 is 70% of 20
