Answer:
The surface area of the net shown is: 88 
Step-by-step explanation:
Break up the different shapes in the net:
Let's take the big square first:
It has a side of 5in and a base of 4in.
We multiply both these values to get 20
Lets look at the small rectangular box now:
It has a side of 3in and a base of 4in.
We multiply both these values to get 12
There are two big squares so we add up their surface areas:
20
+ 20
= 40
There are 4 small rectangular squares so we add up their surface areas:
12
+ 12
+ 12
+ 12
= 48
Now we add up the big square and small rectangular squares values:
40
+ 48
= 88
Therefore the answer is 88
I will translate
"five more than" 5+ "twice a number" 2n
5+2n is the expression
I think the answer may be that an event is as likely as not to happen when the probability of the event happening is 50%, and the probability of the event not happening is 50%. Like a coin toss, the chance you will flip a "heads" is 1/2 or 50%, and the chance that you WON'T flip a heads is also 1/2 or 50%
