Let x be the first number each pair and y is the second of each
As you see 1x is 3y
And. 2x is 3*3y= 9y
3x = 3*3*3y= 27y
Last 4x =3*3*3*3y= 81y
So y = 3^x
Answer:
D. (6) is the distance between 6 and 0, and the distance is negative from 6 to 0
Step-by-step explanation:

Answer:
45 inches
Step-by-step explanation:
85-40=45
b=45
how I know?
use the formula c^2-a^2=b^2
85 being c, a being 40 and b being 45
