Question

1) (4-x)^2-8(3-x) при x=-0,3​

Answer 1

Ответ:

Пошаговое объяснение:

=16-8х+х^2 - 24+8х=х^2 - 8

(-0,3)^2 - 8=0,09-8=-7,91

Answer 2

To evaluate the expression (4-x)^2 - 8(3-x) at x = -0.3, follow these steps:

Step 1: Replace x with -0.3 in the expression. Step 2: Perform the calculations.

Let's proceed with the calculation:

(4 - x)^2 - 8(3 - x)

Step 1: Substitute x with -0.3:

(4 - (-0.3))^2 - 8(3 - (-0.3))

Step 2: Simplify the expression:

(4 + 0.3)^2 - 8(3 + 0.3)

(4.3)^2 - 8(3.3)

18.49 - 8(3.3)

18.49 - 26.4

Step 3: Final result:

-7.91

So, when x = -0.3, the value of the expression (4-x)^2 - 8(3-x) is -7.91.
