Answer:

A_t=2B^3 \ cm^2

Step-by-step explanation:

<u>Area Of Squares </u>

The area of a square of side length B centimeters is

A=B^2 \ cm^2

If we have two rows, each one containing B of those squares, then the total area is

A_t=(2B)A=(2B)B^2 \ cm^2

Simplifying

\boxed{A_t=2B^3 \ cm^2}

Tell which equation you use to solve for one of the variables when solving the system by substitution: 2x + 3y = 5 or 4x - y =3
mixas84 [53]
You can using any equation you want to solve for one of the variables. For instance,  if you want to solve for x you turn one of the equations so y is by its self
<span>
2x + 3y = 5
 4x - y =3

I am going to use </span>4x - y =3
-y = -4x + 3
y = 4x -3
Now you can substitute 4x - 3 for y  in 2x + 3y = 5 and solve for x
2x + 3y = 5
2x + 3(4x - 3) = 5
