what is the value of the expression below when z = 4?
8z - 6
answer attempt 1 out of 2

Explanation:

Step1: Substitute z = 4 into the expression

We have the expression \(8z - 6\). Substitute \(z = 4\) into it, so we get \(8\times4 - 6\).

Step2: Calculate the multiplication first

According to the order of operations (PEMDAS/BODMAS), we first calculate the multiplication. \(8\times4 = 32\), so the expression becomes \(32 - 6\).

Step3: Calculate the subtraction

Now we calculate \(32 - 6 = 26\).

Answer:

26
