Question

Use the Associative Property of Addition to write an expression equivalent to (x+ 9) + 4. Which expression is equivalent to (x+ 9) + 4 by the Associative Property of Addition?

O A. x+9 +4
O B. (x+4) +9
O C. x+ (9+4)
O D. 4+ (x +9)

Answer 1

The expression equivalent to (x+ 9) + 4 using the Associative Property of Addition is x + (9 + 4), which is option C.

Step-by-step explanation:

The question asks to use the Associative Property of Addition to write an expression equivalent to (x+ 9) + 4. The Associative Property of Addition states that the way in which numbers are grouped in an addition problem does not change the sum. In other words, if you have three or more numbers, you can add them together in any order, and you will still get the same result. This means that (x + 9) + 4 is equivalent to x + (9 + 4). Therefore, the equivalent expression using the Associative Property of Addition is:

C. x+ (9+4)
