Question

Simplify, showing your steps. Tell the property you used in each step.
2(a + 4) + -8

Answer 1

2(a + 4) + (-8)
First we need to distribute through the parenthesis...this will eliminate the parenthesis. This is called the distributive property.
To do this, you take the number or the sign before the parenthesis, and multiply it by everything in the parenthesis.
2*a + 2*4 - 8 (the 8 becomes negative because a + x - = - )
2a + 8 - 8 Now you combine like terms
2a < -- this is all that is left because the 8's cancelled each other out.
