Mr. Walker asked his students to use the associative property to find an expression that is equivalent to (13 + 15 + 20) + (20 +
2 answers:
Answer:
The correct option is four.
Step-by-step explanation:
The associative property implies that the values are added however we want, i.e. the numbers can be grouped in any way and the answer would still be the same.
The associative property of addition is:
The expression provided is:
(13 + 15 + 20) + (20 + 47 + 18)
The answer provided by four students are:
Jeremy : (20 + 13 + 15) + (20 + 47 + 18)
Layla : (20 + 47 + 18) + (13 + 15 + 20)
Keith : (13 + 20) + (20 + 47 + 18) + 15
Melinda : (13 + 15 + 20 + 20) + (47 + 18)
So, all the four students correctly applied only the associative property to rewrite the expression.
The correct option is four.

I'm assuming this is multiple choice and you forgot to post the answers. I'll take a guess and say it probably looks something like this:
Because you can't take the square root of a negative number without getting an imaginary result, resulting in the function having a closed domain limit.
