Question

7(6-t) - (1 – 7)(1 +7) при t =12​

Answer 1

Ответ:

6-t-(-6)*8=6-t+6*8=6-t+48=54-t

t=54-12=42

Answer 2

To calculate the expression 7(6-t) - (1 - 7)(1 + 7) when t = 12, you'll substitute t with 12 and perform the calculations:

7(6 - 12) - (1 - 7)(1 + 7)

First, simplify the expressions within the parentheses:

7(-6) - (-6)(-8)

Now, calculate the multiplications:

-42 + 48

Finally, add the two results:

-42 + 48 = 6

So, when t = 12, the value of the expression is 6.
