X=36. You just make the equation: X+9=45. Then you subtract 9 from 45 like this: -9 -9. That gives you 36
If you’re being bullied there’s a lot you can do. While different tactics work for different people, the first thing you should do is try to work it out yourself.
Depending on how bad the bullying is (and as long as you don’t feel at risk, scared or physically threatened) you might want to try and work it out yourself – as a first step.
The more empowered you are, and the more you can help yourself, the better chance you have to stop the bully.
If the bully doesn’t change their behavior, that’s when talking to someone else can be really helpful.
The bully wants you to react. Their goal is to take away your power, make you sad and scared. And if you show them you are not sad and scared, they will often lose interest and they cannot take away your power.
Remember they want to upset you constantly so you get angry. If you don’t get angry, the bully will lose their own power.
Remember that bullies are human - they eat, sleep and live just like you do. The only difference is that you are NOT a bully! Bullies act the way they do because they lack the attention or parental love and nurturing that you have. They are insecure and bully only to feel powerful.
Bullies look for a reaction from you and often lose interest if they aren't given the satisfaction of getting one.
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape.
Let the missing number be x
Mean is the total sum of data over the number of data therefore,
(11+20+x+3+1) / 5 = 9
Then simplify
(35 + x) / 5 = 9
Then multiply 5 to both sides
35 + x = 45
Then subtract 35 to both sides to find x
X= 10
Hope this helps!
