Answer 2

Ответ:

-6.3

Пошаговое объяснение

-3b+2b=-b

-3c+4c=c

3bc-3bc=0

-b=-2.6

c=-3.7

-b+c=-2.6-3.7=-6.3

Answer 3

To solve the expression -3b-3c+3bc+2b+4c-3bc for the given values of b = 2.6 and c = -3.7, we substitute these values into the expression and perform the calculations.

Substituting b = 2.6 and c = -3.7 into the expression: -3(2.6) - 3(-3.7) + 3(2.6)(-3.7) + 2(2.6) + 4(-3.7) - 3(2.6)(-3.7)

Simplifying the expression using the given values: -7.8 + 11.1 - 23.562 - 5.2 - 14.8 + 23.562

Performing the calculations: -7.8 + 11.1 - 23.562 - 5.2 - 14.8 + 23.562 = -16.9

Therefore, when b = 2.6 and c = -3.7, the value of the expression -3b-3c+3bc+2b+4c-3bc is -16.9.
