Answer 1

Let's break down the evaluations of both lines of expressions step by step:

Line 1: \([(−2)+4]+3\)

1. Calculate \((-2) + 4\): \[ (-2) + 4 = 2 \]

2. Add 3: \[ 2 + 3 = 5 \]

So, Line 1 simplifies to: \[ 5 \]

Line 2: \((-2) + [4 + 3]\)

1. Calculate \([4 + 3]\): \[ 4 + 3 = 7 \]

2. Add \((-2)\): \[ (-2) + 7 = 5 \]

So, Line 2 simplifies to: \[ 5 \]

Summary:

• For Line 1: \([(−2)+4]+3 = 5\)
• For Line 2: \((-2) + [4 + 3] = 5\)

Both expressions equal 5.

Final Answer:

The expressions were correctly simplified to \(5\) for both lines.
