<span>−3|2x + 6| = −12
</span><span>−3(2x + 6) = −12
-6x - 18 = -12
-6x = -12 +18
-6x = 6
x=-1
</span>−3 [-(2x + 6)] = −12
−3 (-2x - 6) = −12
6x +18 = -12
6x = -12 -18
6x = -30
x=-5
<span>answer: x= -5 and x = -1

Answer:
You need a calculator to solve, but here: 7.7
Step-by-step explanation:
u missed a few paranthesis. I solved this instead: (3.71 + (-5.25))(4+(-9))
first subtract 3.71 by 5.25 to get -1.54 then subtract 4 by 9 to get -5. Then you multiply them to get 7.7.

Step-by-step explanation:
the central angle is the same as the arc
mDE= 104°
mFE= 76°
mDEF= 180°
mCFD= 180°
mDFE= 256°
Step-by-step explanation:
12.09 - 8.30 = 3.79
The reason why her answer was wrong is because when the '2' gets slashed into a '1' during carry over, it would have been 11 - 8 = 3 instead of a 4. (the 1st column)
The error that Juanita made is that she made a computational error when subtracting.
