Question

9х-4×(9 × Х+8) при х=5

Answer 1

Ответ:

Пошаговое объяснение:

9х-4*(9*Х+8) = 9x - 36x - 32 = -27x - 32

при х=5

-27*5 - 32 = -135 - 32 = -167

Answer 2

To evaluate the expression 9x - 4(9x + 8) when x = 5, you simply need to substitute the value of x into the expression and perform the arithmetic operations.

Step 1: Replace x with 5 in the expression. 9x - 4(9x + 8) = 9(5) - 4(9(5) + 8)

Step 2: Perform the operations inside the parentheses first. 9(5) = 45 9(5) + 8 = 45 + 8 = 53

Step 3: Substitute the calculated values back into the expression. 9x - 4(9x + 8) = 9(5) - 4(9(5) + 8) = 45 - 4(53)

Step 4: Perform the remaining arithmetic operations. 45 - 4(53) = 45 - 212 = -167

So, when x = 5, the value of the expression is -167.
