Question

3(5x-1)-14(x+8)при x=172

Answer 1

3(5х-1)-14(х+8)
15х-3-14х-112=х-115.
При х=172, то 172-115=57.
Ответ:57

Answer 2

To evaluate the expression 3(5x-1)-14(x+8) when x=172, substitute x=172 into the expression and perform the calculations.

3(5x-1)-14(x+8) = 3(5*172-1)-14(172+8) = 3(860-1)-14(180) = 3(859)-14(180) = 2577-2520 = 57

Therefore, when x=172, the expression 3(5x-1)-14(x+8) evaluates to 57.
