If you want to find out what that number is, then let's call it n
n + 3n (Three times the number) + 12 = 32
Simplify
4n + 12 = 32
Subtract 12 from each side
4n = 20
Divide each side by 4
n = 5
The answer would be 48.
All you would have to do is multiply the height (the straight line) and the length which is the 6.
Answer:
yyyyyyyyyyyyyyy you have high hopes
Problem: 6|-3|-4|5|
Whenever something is in: |21| in the lines, you would just count the number itself.
So it is: 6·3-4·5 which would equal: 6·3-4·5
The answer to 6·3 is 18, so its 18 minus the answer of 5·4 which is 20.
So its: 18-20= -2
