a) 20+9x
b) 9x−20
c) x9+20
d) 20−9x

Answer 1

Using the commutative property, the algebraic expression equivalent to 9x + 20 is 20 + 9x, which aligns with answer choice a).The algebraic expression equivalent to 9x+20 using the commutative property is 20+9x.

Step-by-step explanation:

The question asks us to write an algebraic expression equivalent to 9x + 20 by using the commutative property. The commutative property states that you can change the order of the numbers in an addition or multiplication operation without changing the result. Therefore, applying the commutative property of addition to 9x + 20, we can rewrite the expression as 20 + 9x, which is answer choice a).
