Question

3) 0, 25а - 4с”, где a = 4, с = 3;

Answer 1

0,25а-4с, где а=4; с=3:

0,25*4-4*3=1-12=-11 - это ответ.

Answer 2

It seems like you've provided a mathematical expression and values for the variables. Let's break down the expression and substitute the given values for the variables:

Given expression: 0, 25а - 4с

Given values: a = 4, c = 3

Substitute the values into the expression: 0, 25 * 4 - 4 * 3

Now perform the calculations:

1. 0, 25 * 4 = 1.00
2. 4 * 3 = 12

So, the expression simplifies to: 1.00 - 12 = -11.00

The result of the expression 0, 25а - 4с, with a = 4 and c = 3, is -11.00. Please note that the use of a comma in the expression is unconventional in mathematics. If you meant to use a different symbol, such as a minus sign (-) or a multiplication sign (*), please clarify.
