Answer:
never
Step-by-step explanation:
let k be the scale ratio of two bodies then according to the question
k = a/b -- (1)
let Sa be the surface area of body A and Sb be the surface area of body B , then
according to the relation of scale factor and surface areas

from the above equation ,

as k = a/b from (1)
therefore
hence the ratio of their surface area is 
Answer:
Hi There! There are no solutions to this system.
Step-by-step explanation:
nd When graphing a set of equations, make sure that the slopes are not equivlient. If the slopes are equivlient, the lines are parallel, and parallel lines do not intersect. You can check the slope of the equations to find if they are equal. Both graphs go down by 3 each time they go over 2, making the slope -3/2. If they have the same slope, but a diffrent Y interset, they are parallel. You can also set the equations equal to each other, and when solving find that 7 does not equal 1, or
-3/2X+7=-3/2X+1
+3/2X
7=1
Because this is false, the lines will not intersect.
