10(-8s-k)
(10) (-8s + -k)
(10) (-8s) + (10) (-k)
= -80s - 10k
= -10k-80s
Answer:
surface area of a cuboid=2(L*W)+ 2(L*H)+ 2(W*H)
2(9*5)+2(9*4)+2(5*4)


No. It's the ratio of 37 to 100 .
Also, it can be written as a fraction with whole numbers
on top and bottom. Like this: 37/100 .
So it's a rational number.
