(a + 1)(a² + 2a + 1)
= a(a² + 2a + 1) + 1(a² + 2a + 1)
= a³ + 2a² + a + a² + 2a + 1
= a³ + 3a² + 3a + 1
Answer: b
Answer:
B.
Explanation:
Because the study is relying on the effects of violent video games and how it affects anti-social behavior.
If this was a math problem it'd be:
---> y= effect and signs of anti social behavior.
---> x= violent video games.
--->5= Hours spent playing. (Lets use 5 as a random number to write this as an equation then.)
Equation form:
Most likely would look something like this
(5x=y)
Hope this helped. I know it's late but it came up on my "Selected for you" section so I decided I'd answer it.

Answer:
A princess is stuck at the top of a tower that is 20 ft tall. To get down she shoots an arrow with rope attached into the ground and it lands 15 ft away from the tower. how long is the rope to safely guide her onto the ground.
Step-by-step explanation:
using the Pythagorean theory which is a squared plus b squared equals c squared you will see that 20 squared plus 15 squared will equal 625. Once you have that answer you find the square root of 625 which will give you your overall answer of 25.
