Question

3,4х+5,7х+6,6х-4,7х При х=3,6;0,8;10

Answer 1

3,4x + 5,7x + 6,6x - 4,7x = 11x

При x=3,6:

3,6*11 = 39,6

При x=0,8:

0,8*11 = 8,8

При x=10:

10*11 = 110

Answer 2

To evaluate the given expression for different values of x, you need to substitute each value of x into the expression and perform the calculations. Let's calculate the expression for x = 3.6, x = 0.8, and x = 10.

The given expression is: 3.4x + 5.7x + 6.6x - 4.7x

1. For x = 3.6: Substitute x = 3.6 into the expression: 3.4(3.6) + 5.7(3.6) + 6.6(3.6) - 4.7(3.6)

   Calculate the result: 12.24 + 20.52 + 23.76 - 16.92 = 39.6

2. For x = 0.8: Substitute x = 0.8 into the expression: 3.4(0.8) + 5.7(0.8) + 6.6(0.8) - 4.7(0.8)

   Calculate the result: 2.72 + 4.56 + 5.28 - 3.76 = 8.8

3. For x = 10: Substitute x = 10 into the expression: 3.4(10) + 5.7(10) + 6.6(10) - 4.7(10)

   Calculate the result: 34 + 57 + 66 - 47 = 110

So, the results of the expression for x = 3.6, x = 0.8, and x = 10 are 39.6, 8.8, and 110, respectively.
