Answer 2

To calculate the expression 7×65 + 7 + 3×35 + 3×55, we follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

7×65 = 455 3×35 = 105 3×55 = 165

Now, we can substitute these values back into the expression:

455 + 7 + 105 + 165

Next, we add the numbers together:

455 + 7 = 462 462 + 105 = 567 567 + 165 = 732

Therefore, 7×65 + 7 + 3×35 + 3×55 equals 732.
