Answer:
3n + 2
Step-by-step explanation:
-n+(-4)-(-4n)+6
= -n -4 +4n +6 [positive plus negative = negative; ∴ +(-4) = -4
=4n - n +6 - 4 negative plus negative = positive; ∴ -(-4n) = 4]
now subtract n from 4n and subtract 4 from 6
=3n + 2
Answer:
x=12
Step-by-step explanation:
2x-4=20
2x=24
x=12
$21.50(40) + $31.88 (62-40)
$21.50(40) + $31.88(22)
$860 + $701.36
$1561.36

Hello there i hope you are having a good day :)
So you have got AB in a straight line this for a straight line would equal to 180° Then all you would have to do is to work out angle X you would do
42° + 29° = 71° and then you would take away it from 180° - 70° = 109°
So X would equal to 109°
Hopefully that helps you ❤
