2. \(((18 - 9) \times 4 + 8 + 35 - 5)\)

MCQ: What is the value of the expression \((12 - 8 + 4 + 9 \times (40 + 4))\)?

A) \(352 + 36x\)

B) \(356 + 36x\)

C) \(356 - 36x\)

D) \(352 - 36x\)

Answer :

Answer:

To solve the expression (12 - 8 + 4 + 9x(40 + 4)), we can use the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

1. First, we simplify the expression inside the parentheses:

(40 + 4) = 44

2. Next, we perform the multiplication:

9x44 = 396

3. Now, we can simplify the addition and subtraction from left to right:

12 - 8 + 4 + 396 = 4 + 4 + 396 = 8 + 396 = 404

Therefore, the value of the expression (12 - 8 + 4 + 9x(40 + 4)) is 404.
