Question

18xy+6x-24y-8 при x=1 y=0.45

Answer 1

Вот это ответ 8,1+6-10,8-8=-4,7

Answer 2

To evaluate the expression 18xy + 6x - 24y - 8 when x = 1 and y = 0.45, simply substitute the given values into the expression and perform the arithmetic:

18xy + 6x - 24y - 8

Replace x with 1 and y with 0.45:

18(1)(0.45) + 6(1) - 24(0.45) - 8

Now, perform the calculations:

18 * 1 * 0.45 = 8.1 6 * 1 = 6 24 * 0.45 = 10.8

So, the expression becomes:

8.1 + 6 - 10.8 - 8

Now, perform the final calculation:

8.1 + 6 - 10.8 - 8 = 5.3

Therefore, when x = 1 and y = 0.45, the value of the expression 18xy + 6x - 24y - 8 is 5.3.
