Question

Find 6A – 5B. Picture below:

Answer 1

@robz8

Answer 2

so when you say '6A'

i'm assuming that means multiply everything inside the matrix by 6

do the same thing for 5B

and just like the last problem, subtract the corresponding numbers in each matrix

Answer 3

\[\left[\begin{matrix}2 & 27 & 51 \\ 39 &13 &-60\end{matrix}\right]\] this is what I got @robz8

Answer 4

looks about right
