Answer
[-12.6 ..... -4.62]
[-12.6 .......8.4]
[4.2.... -12.18]
Work Step by Step
.The scalar is -4.2.You have the matrix:
[3 ..... 1.1]
[3 .......-1]
[-1.... 2.9]
Multiply each element by the scalar:
[3(-4.2) ..... 1.1(-4.2)]
[3(-4.2) .......-1(-4.2)]
[-1(-4.2).... 2.9(-4.2)]
The new matrix:
[-12.6 ..... -4.62]
[-12.6 .......8.4]
[4.2.... -12.18]
