Help with math/algebra problem!?
The answer is supposedly 66, but I keep getting -66.... am I right or wrong? THANKS math friends!
-6 + 4(10b - 11) - 8(5b + 2)
It just needs to be simplified....
I got this:
-6 + 40b - 44 -40b -16
-6 - 44 -16 = -66
Thanks! I have the answer key, but it is photocopied, so maybe the - sign is too faint. Appreciate it!
