It is thanks to Amerigo Vespucci and Christopher Columbus that the land was discovered, and so spurred other countires such as Spain and Portugal into what now is called the Age of Discovery. Not be outdone by the other, both of these countries wished to seize control of the raw materials and land available for their own.

All quadrilaterals are alike because all of them have four sides, are coplanar, have two diagonals, and the sum of their four interior angles equals 360 degrees. Quadrilaterals can be different because they may or may not have parallel sides or equal sides, and there are many different types of quadrilaterals with special properties.
f(x) = x? & g(x) = 2x + 1
(f+g)(x) = f(x) + g(x)
= (x2) + (2x + 1)
= x2 + 2x + 1,
(f + g) (x) = x2 + 2x + 1
(f-g)(x) = f(x) - g(x)
= (x2) - (2x + 1)
All of these affect it in some way
