<span>I doubt it. Most of the world was undiscovered by the other. Once the explorers did discover the other regions, they brought with them the seeds of the fruits and vegetables of the area and spread it around Potatoes and corn and tobacco were cultivated by the Aztecs I believe.

You can use substitution method
x - y = 7
(x+y)^2=289
So
Since the square of their sum is 298, their sum without being squared is the square root of 289.
Hence,
x - y = 7
x + y = 17
By subtracting you get the following:
= (0) -2(y)=-10
So -2y=-10
y=-10/-2
y=5
Now, plug in y in both equations to get x
x - (5) = 7
x + (5) = 17
Multiply each equation with its opposite y variables
(5) x - (5) = 7
(-5) x + (5) = 17
= 5x -25 = 35
-5x -25 = -85
Now subtract the equations
= 10x + (0) = 120
10x = 120
x = 120/10
x = 12

In 1846, the Oregon boundary dispute between the U.S. and Britain was settled with the signing of the Oregon Treaty. The British<span> gained sole possession of the land north of the 49th parallel and all of Vancouver Island, with the United States receiving the territory south of that line.</span>
