Okay, so in this question we have a format crisis and we need to find the matrix P plus Eddie. Right, so right down the metric speed and and B. And D. Over here. Okay now we need to multiply these two matrices, so nine multiplied by seven. That is 63 seven. multiplied by 1:37. Bye. Multiplied by -4. That is -20. Mind multiplied by -7, that is -63, seven. multiplied by -6, that is -42, three. multiplied by minus for that is -12, eight, multiplied by seven. That is 56 3, multiplied by one, that is three. And the six multiplied by Why? That is 30 eight multiply by -7. That is -56, Three multiplied by -6, that is -18 and…
