280. 8 = 23 10 = 2 x 5 14 = 2 x 7 lcd = 23 x 5 x 7 = 280
-4-x = 10 -x = 10+4 -x = 14 x = -14
(5 x 1000000) + (2 x 100000) + (3 x 10000) + (7 x 1000) + (8 x 100) + (8 x 10) + (8 x 1)(5 x 10^6) + (2 x 10^5) + (3 x 10^4) + (7 x 10^3) + (8 x 10^2) + (8 x 10^1) + (8 x 10^0)
The ratio of lengths is 4:14 or 8:28 ie 2:7 So 10 = 2*5 means that x = 7*5 = 35 units
x + y = 10 y = x + 8 so, x + (x + 8) = 10 2x + 8 = 10 2x + 8 - 8 = 10 - 8 2x = 2 x = 1 and y = 9 because y = x + 8 y = 1 + 8 y = 9
