Question

evaluate the following expression for k = 4. 5k + 9 - 3

Explanation:

Step1: Substitute \( k = 4 \) into the expression

Substitute \( k = 4 \) into \( 5k + 9 - 3 \), we get \( 5\times4 + 9 - 3 \).

Step2: Calculate the multiplication

Calculate \( 5\times4 = 20 \), so the expression becomes \( 20 + 9 - 3 \).

Step3: Calculate the addition and subtraction

First, \( 20 + 9 = 29 \), then \( 29 - 3 = 26 \).

Answer:

26
