Original Question:
100 - [(25/5) x 10] = ?
Note: Always answer what's inside FIRST. In this case, the main ts the brackets, but there's also parenthesis in it too. So solve that.
→100 - [(5) x 10] = ?
Now, solve what's inside the brackets.
→100 - [50] = ?
Well, you can get rid of the brackets.
→100 - 50 = ?
Subtract!
→100 - 50 = 50
Solution:
50
-20 because after the the thermometer hits zero the more negative the temperature gets the colder it is
Yes, that is true, you have to simplify -42/-45 to be able to see if they are equivalant.
Area of a square is a^2 where a is side length
if u triple the side then it is 3a
A=(3a)^2=9a^2
