1 and 24
2 and 12
3 and 8
4 and 6
Answer:
Step-by-step explanation:
18x-6=120
18x=120+6
18x=126
x=126÷18
x=7
The scale factor of two means you need to multiply the original length by 2:
9 x 2 = 18
The new length would be 18 cm.
Let the set of all Odd multiples of 9 between 2 and 82 be denoted by D, then, using set-builder notation,

The odd multiples of 9,
, in the range
form the set

Each member of the set is a term of the arithmetic progression

where the values of
range from 0 to 4, or 
Putting these facts together, we get the result
