Question

6х-8х при х2,3 у5,8=​

Answer 1

Объяснение:

6х-8х=6×2,3+8×5,8=13,8-46,4

Answer 2

To evaluate the expression 6x - 8x when x is 2.3, we can substitute the value of x into the expression and perform the calculation.

Let's substitute x = 2.3 into the expression: 6(2.3) - 8(2.3)

Now, calculate the multiplication first: 13.8 - 18.4

Finally, subtract: -4.6

Therefore, when x is 2.3, the value of 6x - 8x is -4.6.
