Question

Use the commutative property to write an equivalent expression to 4g + 13, and show that they are equivalent for g = 10 and g = 2. Complete the statements.

If you change the order of the terms you can create the equivalent expression 13 × 4g13 + 4g410 + 134g × 13.

After substituting 10 for g, the expressions are 4 + 1314 + 134(10) + 13410 + 13 and 1 + 3 + 4 + 1013 + 4(10)13 + 1413 + 410.

After substituting 2 for g, the expressions are 4(2) + 13 and 13 + 4(2).

The expressions are equivalent because they both have a value of 182753423 when g = 10 and a value of 2155138 when g = 2.

Answer 1

Boxes are: 13+4g, 4(10)+13, 13+4(10), 53, 21

I get emails from other people to say their answers have been blocked, sometimes questions are blocked. I regularly release them if they appear to be genuine, even if some answers are wrong. I also delete inappropriate questions and answers when I find them; but there are tens of thousands of them, and they are coming in all the time.
