-9 = 1.1k + 3.5
-3.5 -3.5

-12.5 = 1.1k
/ 1.1 / 1.1

-11.4 = k

Subtract 3.53.5 from both sides
−9−3.5=1.1×kSimplify -9-3.5−9−3.5 to -12.5−12.5
−12.5=1.1×kDivide both sides by 1.11.1
− 12.5/1.1 = k
Simplify 12.5/1.1 to 11.363636
−11.363636=k
then switch sides
k=−11.363636

I could be wrong?? Let me know if this helped and if it's right

Step-by-step explanation:

$A=\begin{bmatrix}2&3\\4&7\end{bmatrix}\\\\A^{-1} =\begin{bmatrix} \dfrac{7}{2} & \dfrac{-3} {2}\\-2&1 \end{bmatrix}\\\\A*A^{-1}=1\pi_2=T\\\\A^2+3T=\begin{bmatrix} 14&27\\36&61 \end{bmatrix}+\begin{bmatrix} 1&0\\0&1 \end{bmatrix}=\begin{bmatrix} 17&27\\36&64 \end{bmatrix}$
