Question

14,7⋅12−2⋅14,7+12⋅15,3−2⋅15,3.

Answer 1

Ответ: Вроде 300

Объяснение:

14,7*(12-2)+15,3*(12-2)=10*(14,7+15,3)=30*10=300

Answer 2

To solve this expression, you need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Let's solve the expression step by step:

1. Calculate each multiplication and subtraction operation first:

   • $14.7 \cdot 12 = 176.4$
   • $2 \cdot 14.7 = 29.4$
   • $12 \cdot 15.3 = 183.6$
   • $2 \cdot 15.3 = 30.6$

2. Now, substitute these values back into the expression:

   $14.7 \cdot 12 - 2 \cdot 14.7 + 12 \cdot 15.3 - 2 \cdot 15.3$

   becomes

   $176.4 - 29.4 + 183.6 - 30.6$

3. Now, perform the additions and subtractions from left to right:

   $176.4 - 29.4 + 183.6 - 30.6 = 120.0 + 183.6 - 30.6 = 303.6 - 30.6 = 273.0$

So, the final result of the expression $14.7 \cdot 12 - 2 \cdot 14.7 + 12 \cdot 15.3 - 2 \cdot 15.3$ is $273.0$.
