Brums [2.3K]

Answer: -13, -12.9

Step-by-step explanation:

pull out that HANDY DANDY calculator dog because we are about to go on a MATH ADVENTURE oh yea.

ok first make sure it is a reasonably good calculator but you can even use a calculator on your chromebook, maybe an online one? we need one that gives us PARENTHESES.

ok now you are going to want to input into this calculator, (335 / 2) in other words 335 divided by 2. what do we get? we get

167.5

ok cool WE ARE MAKING PROGRESS HERE!!!

now i want you to look for the square root button, it looks like a radical like this

\sqrt[2]{} or MAYBE IT DOESNT EVEN HAVE THE 2 and it is just: \sqrt[]{}

and press it, it should give you the square root but we want to find \sqrt{167.5}

and we get.....

12.942...

MY GOD THAT IS A SUPER LONG NUMBER! but its ok we only need 3 digits after the decimal. now notice that there is a negative sign behind that radical. thats radical, dude, ok now we have -12.942...

if we round to the nearest INTEGER then we need to round to the nearest WHOLE NUMBER which is

-13

and the nearest TENTH is one number after the decimal place so it would be...

-12.9

SURFS UP DUDE

P.S. i mention the parentheses because you can even do \sqrt{(335/2)} (press square root button then opening parentheses then 335 / 2 then close parentheses and hit equal sign or ENTER) but dont forget that EPIC NEGATIVE SIGN!!!!!!!
