Question

3,4x+5,7х+6,6х-4,7х если х = 3,6; 0,8;10;

Answer 1

3,4х+5,7+6,6х-4,7х - упрощаем

х(3,4+6,6-4,7)+5,7= 5,3х+5,7

при х=3,6                  5,3*3,6+5,7= 24,78

при х=0,8                  5,3*0,8+5,7= 9,94

при х=10                   5,3*10+5,7= 58,7

Answer 2

To calculate the given expression for different values of x, simply substitute each value of x into the expression and perform the calculations. Let's do it step by step for each value of x:

1. When x = 3.6: 3.4 * 3.6 + 5.7 * 3.6 + 6.6 * 3.6 - 4.7 * 3.6 = 12.24 + 20.52 + 23.76 - 16.92 = 39.6

2. When x = 0.8: 3.4 * 0.8 + 5.7 * 0.8 + 6.6 * 0.8 - 4.7 * 0.8 = 2.72 + 4.56 + 5.28 - 3.76 = 8.8

3. When x = 10: 3.4 * 10 + 5.7 * 10 + 6.6 * 10 - 4.7 * 10 = 34 + 57 + 66 - 47 = 110

So, the results for each value of x are as follows:

• For x = 3.6, the result is 39.6.
• For x = 0.8, the result is 8.8.
• For x = 10, the result is 110.
