question 3 (1 point)
evaluate $6x - 2^2$ if $x = 10$
12
64
606
56

Explanation:

Step1: Substitute \( x = 10 \) into the expression

We have the expression \( 6x - 2^2 \). Substitute \( x = 10 \), so it becomes \( 6\times10 - 2^2 \).

Step2: Calculate the exponent

First, calculate \( 2^2 \). \( 2^2 = 4 \).

Step3: Calculate the multiplication

Next, calculate \( 6\times10 = 60 \).

Step4: Subtract the results

Now, subtract the two results: \( 60 - 4 = 56 \).

Answer:

56
