ANSWER: -60
EXPLANATION: To solve for (-10) - |(-20) – (+30) |, we need to do:
−10−| −20 − 30|, which equals −10−|−50|. Next, we do −10−50, which is -60.
−10−|−20−30|
= −10−|−50|
= −10−50
= −60
They're not congruent.
If you count the numbers between AC and BE, they're different.
AC - goes from -7 to 0, which is 7 spaces
BE - goes from -2 to 6, which is 8 spaces
