Question

PLEASE

Answer 1

Answer:

  a) 3c

  b) ab

  c) -ab

Step-by-step explanation:

For x > 0, |x| = x. This lets us remove the absolute value symbols in parts (a) and (b):

a. |3c| = 3c . . . when c > 0

b. |ab| = ab . . . when ab > 0

c. The absolute value function returns the opposite of its argument when that argument is negative:

  |ab| = -ab . . .  when ab < 0

Answer 2

A. 3c, b. ab, c. -ab :))
