Answer:
x^2+2xy+y^2
Step-by-step explanation:
(x + y)(x + y)
FOIL
first x*x = x^2
Outer x*y = xy
inner: y*x = xy
last y*y = y^2
add together
x^2+xy+xy+y^2
Combine like terms
x^2+2xy+y^2

Answer:
nl
Step-by-step explanation:
wider the angle, the side opposite to it will be big
let's take ∆lnm angle nlm = 180-(62+55)=180-117=63
take ∆lnp, angle pln = 180-(66+58)=56
angle l = 56+63 = 119
angle p iz the greatest, so side ln must be longest
The real answer is either A. Or from what I've been taught, Columbus thought that he could sail around the world to reach to India and did NOT know there were other lands. And he landed in America and he thought it was India.
