Chapter 7, Problem 37RE

(a)

To determine

To calculate: The value of $A+B$, where, $A=\left[\begin{array}{cc}2& -2\\ 3& 5\end{array}\right]$ and $B=\left[\begin{array}{cc}-3& 10\\ 12& 8\end{array}\right]$.

(b)

To determine

To calculate: The value of $A-B$ for the matrices, $A=\left[\begin{array}{cc}2& -2\\ 3& 5\end{array}\right]$ and $B=\left[\begin{array}{cc}-3& 10\\ 12& 8\end{array}\right]$.

(c)

To determine

To calculate: The value of $4A$ for the matrices $A=\left[\begin{array}{cc}2& -2\\ 3& 5\end{array}\right]$ and $B=\left[\begin{array}{cc}-3& 10\\ 12& 8\end{array}\right]$.

(d)

To determine

To calculate: The value of $2A+2B$ for the matrices, $A=\left[\begin{array}{cc}2& -2\\ 3& 5\end{array}\right]$ and $B=\left[\begin{array}{cc}-3& 10\\ 12& 8\end{array}\right]$.
