Question

using algebra tiles, show a model of x + 3.

Explanation:

Step1: Understand algebra - tile representation

Algebra tiles use a long - rectangle for the variable \(x\) and a small square for the constant 1.

Step2: Analyze the expression \(x + 3\)

The expression \(x+3\) has one \(x\) and three 1s.

Answer:

The first option (a long blue rectangle with \(x\) on it and three yellow squares with 1 on each) is the correct model of \(x + 3\).
