Best ResponseYou've already chosen the best response.1hints: Step 1: substitute all the values of a, b and c into the expression. Step 2: Evaluate the expression within the   (absolute value symbols). Step 3: Evaluate the absolute value functions, i.e. remove the   symbols appropriately Step 4: Evaluate the resulting expression, that's your answer.

Best ResponseYou've already chosen the best response.15 does not turn into positive by itself. You need to complete step 2 first, i.e. reduce the a+b into a single value. Values turn positive only when there is a single number inside the   symbols. See example above.

Best ResponseYou've already chosen the best response.0The expression is: a + b + c Change the values of a, b and c, the values they represent, in the case: a = –5, b = 8, and c = –13 That's: 5 + 8 + 13 The module ( x ) means that no matter the signal that the calculation result, it will always be positive. So: 5 + 8 + 13 3 + 13 3 + 13 = 16 C = 16

Best ResponseYou've already chosen the best response.1Sorry, c is 13, so 3+c=16, is correct.
