1/10 in first row

1/20 in second row

1/5 in third row

Step-by-step explanation:

it is simple, take first row, and look what is required to get 1,

here 5*2 is 10, so to get 1 we need to divide with 10

in second row, 20*1 is 20, so we need to divide with 20

and in third row 10* ½ is 5, so we need to divide with 5

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
