Answer 1

Ответ:

80

Пошаговое объяснение:

39b−18b+14b−25 = 39×3-18×3+14×3-25= 80

Answer 2

To calculate the value of the expression 39b - 18b + 14b - 25 when b = 3, simply substitute the value of b into the expression and perform the arithmetic:

39b - 18b + 14b - 25

Substitute b = 3:

39(3) - 18(3) + 14(3) - 25

Now calculate each term:

117 - 54 + 42 - 25

Combine the terms:

80 - 25

Finally, calculate the result:

55

So, when b = 3, the expression evaluates to 55.
