What point if any is on both of the following lines?

2x-7y=9
4x-14y=-18

No Solution.

Step-by-step explanation:

2x-7y=9

4x-14y=-18

-2(2x-7y)=-2(9)

4x-14y=-18

-4x+14y=-18

4x-14y=-18

0=-36

no solution

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
