Answer:
your median is 17.445
Step-by-step explanation:
put them in order least to greatest
13.64,15.25,19.64,22.25
15.25+19.64=34.89
34.89/2=17.445
All you have to do is move the denominator on the other side, by multiplying.
a-10
------- = -9
20
multiply 20 x -9
= -180
then it becomes a-10=-180
+10 +10
a=-170
Not sure what x' means but
seems to be the reverse distributive property
normally written as
a(b+c)=ab+ac
we can see the similarity
a(x'+y)=ax+ay
distributive property
ANSWER: it’s a square. All sides will look the same after turning because all sides LOOK THE SAME lol.
