Question

5 x (1.2x – 4.3) – 2.3 (6x + 5)

Answer 1

Ответ: 6x-21,5-13,8x-11,5=-7,8x-33

Answer 2

To simplify the given expression, follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction). Let's break it down step by step:

The expression: 5x(1.2x - 4.3) - 2.3(6x + 5)

Step 1: Distribute the terms inside the parentheses/brackets: 5x * 1.2x - 5x * 4.3 - 2.3 * 6x - 2.3 * 5

Step 2: Perform the multiplications within each term: 6x^2 - 21.5x - 13.8x - 11.5

Step 3: Combine like terms: 6x^2 - (21.5x + 13.8x) - 11.5 6x^2 - 35.3x - 11.5

So, the simplified expression is: 6x^2 - 35.3x - 11.5
