Question

Evaluate the expression when x=4: 3x - 2.
A) 6
B) 10
C) 12
D) 14

Answer 1

The expression 3x - 2 evaluated with x=4 gives us 3*4 - 2, which calculates to 12 - 2, and the final answer is 10.

Step-by-step explanation:

To evaluate the expression 3x - 2 when x=4, simply substitute 4 into the expression in place of x and then follow the order of operations.

1. First, multiply 3 times 4 (3x4) to get 12.
2. Then, subtract 2 from 12 (12-2) to get 10.

Therefore, the expression 3x - 2 evaluates to 10 when x equals 4.
