If B is the midpoint of AC, and AC= 8x-20, find BC.
Semmy [17]

Answer:

BC = 4x-10

Write an expression in simplest form that represents the area (in square feet) of the banner.
Agata [3.3K]

The area of the banner, expressed in simplest form, is: <em>(9 + 3x) ft²</em>

<h3>How to Determine the Area of a Rectangle</h3>
  • The area of a rectangle = length × width

The banner given in the image below has a rectangular shape. So, the area of the banner will be determined using the area of a rectangle.

  • length = (3 + x) ft
  • width = 3 ft

Area of the banner = (3 + x)3

Area = (9 + 3x) ft²

Therefore, the area of the banner, expressed in simplest form, is: <em>(9 + 3x) ft²</em>
