Use the matrices below to perform the indicated operation if possible. [o 10] C= 7 -10 87 B = -4 2 1 If the operation is undefined, enter NA. Hint: To create a matrix in Mobius, click on the icon that has three rows of three dots - it's next to the infinity symbol. Specify the appropriate number of rows (horizontal) and columns (vertical). ab sin (a) f 00 2C + B =
