Answer:

  • 8y + 16

Step-by-step explanation:

  • A(l) =  (y + 4)²

<u>Area of small square:</u>

  • A(s) = y²

<u>Shaded area:</u>

  • A = A(l) - A(s)
  • A = (y + 4)² - y² = y² + 8y + 16 - y² = 8y + 16

Wayne's gym locker is a rectangular prism with a width and height of 12
Gnom [1K]

Answer:

Volume = (2890 and 5/8) inches^3

Step-by-step explanation:

Height = 12 and 1/2inches = 25/2

Width = 12 and 1/2inches = 25/2

Length = 6 inches > width = 6 + width

= 6 + (12 and 1/2) = 18 and 1/2

Length = 18 and 1/2 inches = 37/2

Volume of prism = length × breadth × height

Volume of rectangular prism = (25/2)×(25/2)×(37/2)

Volume of rectangular prism = (23125/8) inches^3

Volume of rectangular prism = (2890 and 5/8) inches^3
