Here are a few pieces of advice that will help you and your math skills:
- Take notes. Taking notes during your math classes will help you remember key points and formulas. If you were to ever forget, for example, the quadratic formula, by writing it down you can always reference back to your notes for the quadratic formula.
- Practice! Nobody gets everything right the first time. By practicing and doing the math over and over, you will improve your skills and will better remember them.

Answer:
Step-by-step explanation:
Lets suppose the one side be x and the other side of the rectangle be y
given area ![x*y=650ft^2](https://tex.z-dn.net/?f=x%2Ay%3D650ft%5E2)
implies x = 650/y
Cost = 2*4*x+2*3*y=8x+6y
= 8*650/y + 6y
= 5200/y + 6y
upon differentiating we get
=![-5200/y^2 + 6=0](https://tex.z-dn.net/?f=-5200%2Fy%5E2%20%20%2B%206%3D0)
= 2600/3
y=
= 43.3
x= 15
C(43.3)=
>0 hence it is a minima value
optimizing the result we get
Cost = 8*15+6*43.3 =$ 379.8
