Answer:
The weight can vary from 22.5 to 25.5
Answer:
So option B is the correct answer .
Step-by-step explanation:
Since it is the multiplication of 1 X 3 matrix to 3 X 3 order matrix,
so the resultant product should be 1 X 3 because when we multiply two matrices it is the condition that if A is of order p X q and B is of order q X r,
the product matrix (suppose C ) will be of order p X r.
so the product will be
= [-1*3+2*2+4*0 -1*6+2*4+4*6 -1*1+2*0+4*2]
= [ 1 26 7] .
U is 2
You collect like terms meaning you do 17-8= 9u
9u=18 divide both sides by 9 and get U=9
Add 3 to both sides and you're left z = 2+3
therefore z = 5
