Question

Describe and correct the error.
29. |-13|-|13|
=-13-13
=-26

30. -6(x-5)
=-6x-30

Answer 1

29. The |-13| is actually 13 because it’s in absolute bars. So.. correctly it’s “13-13” which equals 0.

|-13|-|13|
= 13-13
=0

30. The signs are messed up with -6 and -5 that’s all.

-6(x-5)
= -6x+30
