For this case we must simplify the following expression:
We eliminate the parentheses taking into account that:
So:
We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.
Answer:
13 is not the same as 1/3! The division symbol is not a symbol used to connect two numbers, it is used to find their quotient.

Step-by-step explanation:
Answer:
18
Step-by-step explanation:
The hypotenuse of the 45-45-90 triangle is 
The hypotenuse of the 45-45-90 triangle is also the shorter leg of the
30-60-90 triangle
The longer leg = x = shorter leg times 
= 18
