Question

2 + 3а при а = 4, -5

Answer 1

Ответ:

при а = 4 = 14

при а = -5 = -13

Пошаговое объяснение:

2  + 3 * 4 =

1) 3 * 4 = 12

2) 12 + 2 = 14.

2 + 3 * -5 = -13

1) 3 * -5 = -15

2) -15 + 2 = -13

Answer 2

$2 + 3 \times 4 = 14 \\ 2 + 3 \times ( - 5) \\ 1)3 \times ( - 5) = - 15 \\ 2)2 + ( - 15) = 2 - 15 = - 13$

Answer 3

To find the value of the expression "2 + 3a" when a is equal to 4 and -5, we simply substitute these values into the expression and perform the calculations.

1. When a = 4: 2 + 3 * 4 = 2 + 12 = 14

2. When a = -5: 2 + 3 * (-5) = 2 - 15 = -13

So, the value of the expression "2 + 3a" when a is equal to 4 is 14, and when a is equal to -5, the value is -13.
