It depends on which number has the greatest absolute value.
Think about it as money
If you owe me $10, this is shown as -10
Now if I give you back 2 dollars (+2), How much money do I still owe you.
The equation is -10+2
I still owe you 8 dollars which is portrayed as -8
Hope this helps :)
Just multiply bruh
2.55= 2.55 IT IS TRUE
x^2-9x-6=0
Use the quadratic formula to get (9+sqrt(105))/2 or (9-sqrt(105))/2
It is not equal to -2 because the five is a negative so when adding two different integers are subtracted and with a negative sign.
23. because there is a 90 degree angle and then the 67 degree angle, and triangle law says that all angles add up to 180.
