Respuesta :

[tex] c^{2} [/tex] = 144
c = ±[tex] \sqrt{144} [/tex]
c = ±12

Simplify. Combine like terms

62 + 82 = 144

c² = 144

Isolate the c. Note the equal sign. What you do to one side, you do to the other.

Root both sides

c² = 144

√c² = √144

c = √144

c = 12

12 is your answer for c

hope this helps
