Find the values of the variables.
[[-12,-w^(2)],[2f,3]]=[[2k,-81],[-14,3]]
To find the values of the variables w, f, and k, we can set up an equation for each entry in the matrices.
From the first row:
-12 = 2k
k = -6
-w^2 = -81
w^2 = 81
w = ±9
From the second row:
2f = -14
f = -7
So the values of the variables are:
w = ±9
f = -7
k = -6
