Answer 2

Ответ:

$4 {a}^{2} = 4 \times ( - 2.5 {)}^{2} = 4 \times 6.25 = 25 \\ 4 {a}^{2} = 4 \times ( - 2 {)}^{2} = 4 \times 4 = 16 \\ 4 {a}^{2} = 4 \times ( - 1.5 {)}^{2} = 4 \times 2.25 = 9 \\ 4 {a}^{2} = 4 \times ( - 1 {)}^{2} = 4 \times 1 = 4 \\ 4 {a}^{2} = 4 \times ( - 0.5 {)}^{2} = 4 \times 0.25 = 1 \\ 4 {a}^{2} = 4 \times (0 {)}^{2} = 4 \times 0 = 0 \\ 4 {a}^{2} = 4 \times (0.5 {)}^{2} = 4 \times 0.25 = 1 \\ 4 {a}^{2} = 4 \times (1 {)}^{2} = 4 \times 1 = 4 \\ 4 {a}^{2} = 4 \times (1.5 {)}^{2} = 4 \times 2.25 = 9 \\ 4 {a}^{2} = 4 \times (2 {)}^{2} = 4 \times 4 = 16 \\ 4 {a}^{2} = 4 \times (2.5 {)}^{2} = 4 \times 6.25 = 25$

Объяснение:

$- 2 {a}^{2} = 2 \times ( - 2.5 {)}^{2} = 2 \times 6.25 = 12.5 \\ - 2 {a}^{2} = 2 \times ( - 2 {)}^{2} = 2 \times 4 = 8 \\ - 2 {a}^{2} = - 2 \times ( - 1.5 {)}^{2} = - 2 \times 2.25 = - 4.5 \\ - 2 {a}^{2} = - 2 \times ( - 1 {)}^{2} = - 2 \times 1 = - 2 \\ - 2 {a}^{2} = - 2 \times ( - 0.5 {)}^{2} = - 2 \times 0.25 = - 0.5 \\ - 2 {a}^{2} = - 2 \times (0 {)}^{2} = - 2 \times 0 = 0 \\ - 2 {a}^{2} = - 2 \times (0.5 {)}^{2} = - 2 \times 0.25 = - 0.5 \\ - 2 {a}^{2} = - 2 \times (1 {)}^{2} = - 2 \times 1 = - 2 \\ - 2 {a}^{2} = - 2 \times (1.5 {)}^{2} = - 2 \times 2.25 = - 4.5 \\ - 2 {a}^{2} = - 2 \times (2 {)}^{2} = - 2 \times 4 = - 8 \\ - 2 {a}^{2} = - 2 \times (2.5 {)}^{2} = - 2 \times 6.25 = - 12.5$
