Question

Give a numerical example that shows these are not the same expressions. 2(n+5) and 2n+5

Answer 1

Answer: Any number that isn’t 1, 2, -1, or -2 I believe.

Step-by-step explanation: In the first expression, you have to distribute the 2, making it equal to 2n + 10, whereas the first is just 2n + 5.

For example if you were to plug the number 3 into this, you would have 2(3+5), which is 2(8) = 16. Versus the other side, 2(3)+5 = 11

Answer 2

The two are different expressions because when you distibute, you multiply all terms inside the parenthesis with the 2 in the first one: 2(n+5) = 2n + 10.

2n + 10 ≠ 2n + 5.
