As the pen is a triangle, the third side can either be the hypotenuse or a regular side. If the third side is the hypotenuse, it's length would be l= \sqrt{8^2+15^2} = \sqrt{64+225} = \sqrt{289} =17 feet. If the third side is a regular side, than it would be l= \sqrt{15^2-8^2} = \sqrt{225-64} = \sqrt{161}≈12.689 feet. This means your third side can either be 17 feet long or 12.689 feet long.

Answer:

volume of hemisphere = 452.16 ft³

volume of cylinder = 2260.8 ft³

total volume = 2712.96 ft³

1/3 full = 904.32 ft³

Step-by-step explanation:

volume of hemisphere = 1/2(4/3)(3.14)(6³) = 452.16 ft³

volume of cylinder = (3.14)(6²)(20) = 2260.8 ft³

total volume = 452.16 + 2260.8 = 2712.96 ft³

1/3 full = 2712.96/3 = 904.32 ft³

Write the product in standard form: (x+4)(x-4)
Genrish500 [490]

Answer:

x² - 16

Step-by-step explanation:

Use the FOIL method here where

F = first

O = outer

I = inner

L = last

F = x * x = x²

O = -4 * x = -4x

I = 4 * x = 4x

L = -4 * 4 = -16

Combine the terms to get x² - 16.
