Step-by-step explanation:
3x + (2x + 4) is equivalent to (3x + 2x) + 4
because there is no change of signs taking place as there is no (-) sign in front of the brackets
3x + (2x + 4) | (3x + 2x) + 4
3x + 2x + 4 | 3x + 2x +4
5x + 4 | 5x + 4
Answer:
I can use the Associative Property to show that 3x + (2x + 4) is equivalent to (3x + 2x) + 4.
F(4)=24 and F(3)=18
Plug the 4 and the 3 in to the x's and multiply them by 6
