Answer:

12

Step-by-step explanation:

-25 from both side

x^2= 144

then you square root it

x= 12

[tex]\huge\text{Hey there!}[/tex]


[tex]\mathsf{x^2 + 25 = 169}[/tex]

[tex]\text{Subtract 25 to both sides}\downarrow[/tex]

[tex]\mathsf{x^2 + 25 - 25 = 169 - 25}[/tex]

[tex]\text{Simplify it}\downarrow[/tex]

[tex]\mathsf{x^2 = 169 - 25}[/tex]

[tex]\mathsf{x^2 = 144}[/tex]

[tex]\text{Take the square root of the numbers (including the mystery number (x))}\downarrow[/tex]

[tex]\mathsf{x = \pm \sqrt{144}}[/tex]

[tex]\text{So, that means that}\downarrow[/tex]

[tex]\mathsf{x = 12}[/tex]

[tex]\text{Or even:}[/tex] [tex]\mathsf{x = -12}[/tex]


[tex]\huge\text{Therefore, your answer should be:}[/tex]

[tex]\huge\boxed{\mathsf{ x =\ }\frak{12}}\huge\checkmark[/tex]


[tex]\huge\text{Good luck on your assignment \& enjoy your day!}[/tex]
