{[3 x (3 + 6) - 5] + 20} x 2

Question

What is the value if the expression?
A.62
B. 64
C. 77
D. 84

Answer 1

To solve this expression, we follow the order of operations, also known as PEMDAS:

First, we calculate what is inside the inner parentheses:
3 + 6 = 9

Now we rewrite the expression with the calculated value:
[3 x 9 - 5] + 20) x 2

Next, we perform the multiplication:
3 x 9 = 27

Now we rewrite the expression with the calculated value:
[27 - 5] + 20 x 2

Next, we perform the subtraction:
27 - 5 = 22

Now we rewrite the expression with the calculated value:
[22] + 20 x 2

Next, we perform the multiplication:
20 x 2 = 40

Now the expression is:
[22] + 40

Finally, we perform the addition:
22 + 40 = 62

Therefore, the value of the expression is 62.

So, the correct answer is A. 62.
