\text {Hello! Let's Solve this equation!}

\text {Since there is a negative in the problem this tells us that the answer we get will be a negative.}

\text {Here are some tips on dividing/multiplying equations like this.}

\text {Multiplying/Dividing a Positive to a Positive will equal a Positive}\\\text {Multiplying/Dividing a Positive to a Negative will equal a Negative}\\\text {Multiply/Dividing a Negative to a Negative will equal a Positive}\\\text {Multiplying/Dividing a Negative to a Positive will equal a Negative}

\text {Now Divide!}

\text {12/-4=}

\fbox {-3}

\text {As you can see 4 is a negative number so our result came out as a negative number.}

\text {Want to see if your answer is correct? Sure! Do the opposite of Dividing and Multiply!}

\text {-3*-4=12}

\text {Best of Luck!}

\text {-LimitedX}

Walter used the iterative process to determine that √13 is between 3.61 and 3.62.Analyze Walter’s estimation. Is he correct? If
Shkiper50 [21]

The correct option is C no, both 3.61^2 and 3,62^2 are greater than 13.

<h3>Is he correct? If not, what was his mistake?</h3>

To check this, we can just square both of the bounds that he found, and see if it makes sense.

Walter says hat:

3.61 < √13 < 3.62

Then we must have:

(3.61)^2 < 13 < (3.62)^2

The lower bound is 3.61, if we square it we get:

3.61*3.61 = (3 + 0.61)*(3 + 0.61) = 9 + 6*0.61 + 0.61*0.61 = 13.0321

Now, this is larger than 13, so the above inequality is false, which means that Walter is incorrect, because both 3.61 and 3.62 are larger than √13 , then the correct option is C.
