Answer 1

Ответ:

Пошаговое объяснение:

3(а-4в)-5а=3а-12в-5а=-2а-12в

-2*(-72)-12*35=144-420=-276

Answer 2

To evaluate the expression 3(a - 4b) - 5a when a = -72 and b = 35, simply substitute the given values of a and b into the expression and perform the arithmetic:

Step 1: Replace 'a' with -72 and 'b' with 35 in the expression.

3(-72 - 4(35)) - 5(-72)

Step 2: Calculate the values inside the parentheses.

3(-72 - 140) - 5(-72)

Step 3: Continue with the calculations.

3(-212) + 360

Step 4: Multiply.

-636 + 360

Step 5: Perform addition.

-276

So, the value of the expression 3(a - 4b) - 5a when a = -72 and b = 35 is -276.
