Ответ:

83+3x

Пошаговое объяснение:

$7 \times (9 + x) + 4 \times (5 - x) = \\ 63 + 7x + 20 - 4x = 83 + 3x$

Answer 3

To solve the expression, you need to apply the distributive property and then combine like terms. Let's simplify the expression step by step:

7 * (9 + х) + 4 * (5 - х)

Step 1: Apply the distributive property: 7 * 9 + 7 * х + 4 * 5 - 4 * х

Step 2: Multiply the constants: 63 + 7х + 20 - 4х

Step 3: Combine like terms: (7х - 4х) + (63 + 20) = 3х + 83

So, the simplified expression is 3х + 83.
