Find the solution set for this equation M^2-4=0
Helga [31]

Step-by-step explanation:

Hey, there !!

Let's simply work with it,...................

Here, theequation is,

{m }^{2} - 4 = 0

or \:  {m }^{2}  = 4

or \: m  =   +  -  \sqrt{4}

or \: m = + -  \sqrt{ {2}^{2} }

cancelling square and square root we get answer is,

= (+ - 2).

It means the value of m is plus(+) minus(-) 2.

Answer: 24, 33

              2.5, 4.75

              9.5, 11.75

<u>Step-by-step explanation:</u>

It is given that the PERIMETER is BETWEEN 24 and 33

-->          24 < P < 33

Graph:   O------------------O

            24                    33

Perimeter = 2w + 2L

It is given that L = w + 7

Substitute P with 2w + 2L and substitute L with w + 7

                24 <  2w + 2(w + 7) < 33

                 24 < 2w + 2w + 14 < 33    

                  10 <          4w        < 19    

-->             2.5 <          w        < 4.75          

Graph:       O--------------------------O

                 2.5                         4.75

Since L = w + 7, then w = L - 7

Substitute P with 2w + 2L and substitute w with L - 7

                24 <  2(L - 7) + 2L < 33

                 24 < 2L + 2L - 14 < 33    

                 38 <          4L        < 47    

-->             9.5 <          L        < 11.75  

Graph:      O------------------------O

                9.5                          11.75

<em>NOTE: Make sure you use OPEN dots on the graphs.</em>
