Help me please! These are due today.
IrinaVladis [17]

Answer:

{x}^{2}  + 3x

Step-by-step explanation:

1.

Area of shaded region = Area of external rectangle - Area of internal rectangle

= 4x(x + 2) - x(3x + 5) \\  = 4 {x}^{2}  + 8x - 3 {x}^{2}  - 5x \\  = 4 {x}^{2}  - 3 {x}^{2}  + 8x - 5x \\  =  {x}^{2}  + 3x \\

2.

Let the width of the rectangle be x inches.

Therefore, length of the rectangle = (x + 3) inches

A.

Area of rectangle

=(x + 3)\times x\\=x^2 + 3x\\

B.

Width of rectangle = 4 inches

Length of rectangle = 4 + 3 = 7 inches

Area of rectangle = 7*4 = 28 square inches.
