There is the number 12 on each sides,so this has to deal with area. There are 5 sides on a pentagon. 12x5= sixty. Hope this helps.
5(4n-11) - 3n + 20
To get equivalent expression we remove the parenthesis and combine like terms
We distribute 5 inside the parenthesis 4n - 11
5 times 4n = 20n
5 times -11 = -55
So expression becomes
20n - 55 - 3n + 20
Now we combine like terms
20n and -3n are like terms
20n - 3n is 17n, also -55 + 20 is -35
so expression becomes -17n -35

Answer:
Her mom's candle has more citrus in it. Peppermint isn't a citrus scent.
Step-by-step explanation:
8X -2 + 5X + 26 =180
13X +24 = 180
13X = 180-24
13x = 156
X = 156/13
X= 12
Now replacing the value of 12 in 5X +26
5* 12 + 26 = 60 + 26 = 86
