1. The absolute value of a negative number is always negative. True (wrong) absolute value of any number is always positive.

Okay, thank you. Is that the only one you see, that is wrong?

8. nubeer

this is also wrong 2. -2(7 – a) + 16a -14-(-2a+16a [ (-(-2a)= 2a this is what u have to do] -14-14a

9. xXAngelaXx

So instead it would be -14-18a? (I am awful at algebra.)

10. nubeer

-14+2a+16a.. what will you get?

11. xXAngelaXx

-14+18a.

12. nubeer
