Question

4(в+ 0,8)+1,7 при в = 2,3

Answer 1

4(в + 0,8) + 1,7 
4в + 3,2 + 1,7
4в + 4,9
4 * 2,3 + 4,9 = 9,2 + 4,9 = 14,1
Ответ: 14,1

Answer 2

To evaluate the expression 4(в + 0.8) + 1.7 when в is equal to 2.3, we substitute the value of в into the expression and perform the calculations.

Substituting в = 2.3 into the expression, we have:

4(2.3 + 0.8) + 1.7

Now, we simplify the expression:

4(3.1) + 1.7

Multiplying 4 by 3.1 gives us:

12.4 + 1.7

Adding the two values, we get:

14.1

Therefore, when в is equal to 2.3, the expression 4(в + 0.8) + 1.7 evaluates to 14.1.
