Final answer:

Using the order of operations, substitute a=2 into the expression and perform the operations to find the result is 48.

Step-by-step explanation:

To solve the given expression a + (6 x 8) - (1 x a) with a=2, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Here are the steps:

  1. Substitute the value of a into the expression: 2 + (6 x 8) - (1 x 2).
  2. Perform the multiplication inside the parentheses: 2 + 48 - 2.
  3. Finally, perform the addition and subtraction: 2 + 48 = 50 and 50 - 2 = 48.

The correct answer is 48, which corresponds to option C.

The answer is 48 you need to fill in 2 for the value of a so the equation would be 2+(6x8)-(1x2) then you multiply first giving you 2+48-2 then you solve that giving you 48
