Find the values of the variables[-12 -w^2] = [2k -81][2f 3 ] [-14 3]Please show work. Thanks!

The values of the variables are k = -6 , w = ± 9 , f = -7Step-by-step explanation:To solve these problems we will compare the elements inside the [  ][-12 , -w²] = [2k , -81][2f , 3] =  [-14 , 3]That mean:1. -12 = 2k2. -w² = -813. 2f = -14∵ 2k = -12Divide both sides by 2 to find k∴ k = -6∵ -w² = -81Divide both sides by -1∴ w² = 81Take √ for both sides∴ w = ± 9∵ 2f = -14Divide bith sides by 2∴ f = -7The values of the variables are k = -6 , w = ± 9 , f = -7Learn more:You can learn more about simple equation in brainly.com/question/13113987#LearnwithBrainly
