Answer:

±sqrt(E/m)= c

Step-by-step explanation:

E=mc^2

Divide each side by m

E/m=m/m c^2

E/m =c^2

Take the square root of each side

±sqrt(E/m)= sqrt(c^2)

±sqrt(E/m)= c

A rectangle has a length that is twice the width if the perimeter of the rectangle is 96 inches, what is the area of the rectang

S_A_V [24]

Answer:

Step-by-step explanation:

Let the width of the rectangle = x

Length = 2x

Perimeter = 96 inches

2 * ( length + width) = 96

2 * ( 2x + x ) = 96

2 * 3x = 96

3x = 96/2 = 48

3x = 48

x = 48/3

x = 16 inches

Width = 16 inches

Length = 2*16 = 32 inches

Area = length*width

= 32*16

= 512 sq.cm
