(
+ 4)( - 4)
To solve this question you must FOIL (First, Outside, Inside, Last) like so
First:
(x^2 + 4)(x^2 - 4)
x^2 * x^2
x^4
Outside:
(x^2 + 4)(x^2 - 4)
x^2 * -4
-4x^2
Inside:
(x^2 + 4)(x^2 - 4)
4 * x^2
4x^2
Last:
(x^2 + 4)(x^2 - 4)
4 * -4
-16
Now combine all the products of the FOIL together like so...
x^4 - 4x^2 +4x^2 - 16
Combine like terms:
x^4 - 4x^2 +4x^2 - 16
- 4x^2 +4x^2 = 0
x^4 - 16 <<<This is your answer
Hope this helped!

Answer:
seconds could be anything but day was 0 then there would be no seconds, right??? that would basically be true.
Step-by-step explanation:
The shape is a square pyramid, meaning it has one square face and four triangle faces of equal area. Add these areas together to get the total surface area.
Area of Square + 4*Area of Triangle = SA
Area of Square:
2^2=4
Area of Triangle:
0.5*2*3=3
SA=4+4*3
SA=16 meters squared
