Question

2 if x = 5, evaluate eac example 4. a x + 3 d 2x + 4 g 2(x + 2) + x

Explanation:

Part a: \( x + 3 \)

Step 1: Substitute \( x = 5 \)

We substitute the value of \( x \) into the expression \( x + 3 \). So we replace \( x \) with \( 5 \), getting \( 5 + 3 \).

Step 2: Calculate the result

Now we add \( 5 \) and \( 3 \). \( 5+3 = 8 \).

Step 1: Substitute \( x = 5 \)

Substitute \( x = 5 \) into the expression \( 2x + 4 \). This gives us \( 2\times5 + 4 \).

Step 2: Perform the multiplication

First, calculate \( 2\times5 \), which is \( 10 \). So the expression becomes \( 10 + 4 \).

Step 3: Calculate the result

Add \( 10 \) and \( 4 \). \( 10 + 4 = 14 \).

Step 1: Substitute \( x = 5 \)

Substitute \( x = 5 \) into the expression \( 2(x + 2) + x \). We get \( 2(5 + 2) + 5 \).
