Answers

Answer 1

Answer: If you go from -13 to 0, you have an increase of 13 degrees. Then if you go from 0 to 22 you have an increase of 22 degrees. 13 + 22 = 35.
3:00 am to 10:00 am is 7 hours so:
35 degrees/7 hours = 5 degrees/hour

There isn't much you can do other than the guess and check method. For example if you have the square 37. I know that 6 times 6 is 36 so the square root must be very close to 6.

There is this chart that we made in middle school you took one sheet of paper and you folded it four times hot dog style and then you folded it eight times handberger style and then open it back up so that you have a folded booklet almost and then you cut only the folds on the back of the booklet and then you take another piece of paper and you cut it into two strips that will fit in the slits that you just made and then after you have them placed where you want you do all the perfect square from 1 to the power of 2 through about 24 or 25 to the power of 2 and then just go by what the foldable tells you and if you take it from the middle after your done with the foldable and you pull the middle apart there is another whole side that you write the answers to the perfect squares on.

tariq said you can write an equation by setting an expression equal to itself Would an equation like this be true.explain.

Answers

Answer: Yes it is true. We can write an equation by setting an expression equal to itself.

Step-by-step explanation:

Let we take an expression say 2x.

Since we know that any expression is equal to itself, so we can write it as 2x=2x, which does not give any solution or we can say this equation has no solution but we can not say it is false because they are actually equal.

Therefore, we can write an equation by setting an expression equal to itself. It would be a true equattion.

Yes it would.
An equation says two things are equal.
So if you have an expression x + 1 and you set it equal to x + 1
you have x + 1 = x + 1, which is a true and valid equation, not saying it's any useful but it is an equation.
