Step-by-step explanation:
![16x + 2 \div 4 = 2x](https://tex.z-dn.net/?f=16x%20%2B%202%20%5Cdiv%204%20%3D%202x)
![16x + 0.5 = 2x](https://tex.z-dn.net/?f=16x%20%2B%200.5%20%3D%202x)
![16x - 2x = - 0.5](https://tex.z-dn.net/?f=16x%20-%202x%20%3D%20%20-%200.5)
![14x = - 0.5](https://tex.z-dn.net/?f=14x%20%3D%20%20-%200.5)
![x = - \frac{1}{28}](https://tex.z-dn.net/?f=x%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B28%7D%20)

Answer:
38
Step-by-step explanation:
y(y+5)=84
y^2+5y-84=0
Δ=5^2-4*1*(-84)=25+336=361
VΔ=19
y1=(-5+19)/2=7
so P=2*7+2*(7+5)=14+2*12=14+24=38 cm
