Question

complete the expressions. write each answer as a num (2x + 5) + 3 = \boxed{} + (5 + 3) associative pro = 2x + \boxed{} add

Explanation:

Step1: Apply Associative Property

The associative property of addition states that \((a + b) + c = a + (b + c)\). For the expression \((2x + 5) + 3\), we can re - group the terms. So \((2x+5)+3 = 2x+(5 + 3)\). So the first blank should be filled with \(2x\).

Step2: Calculate \(5 + 3\)

We know that \(5+3=8\). So the second blank is filled with \(8\) as \(2x+(5 + 3)=2x + 8\).

Answer:

First blank: \(2x\); Second blank: \(8\)
