Labrys
Athena the Greek goddess sprung out of Zeus's, (King of the gods), head in full battle armour, after he swallowed his wife Metis. (He had complained of severe headache's, so the god of the forge, Hephaestus, split Zeus's head with an ax.) He swallowed her because he feared she was carrying the son that prophesied to overthrow him.
some bloke that invented it
well, some examples are the ox- yoke, the bridle, the ax, the rake, and so on. Hope this helps! :)
disguised himself as a beggar, then shot an arrow through ax holes into the target
first of all, his NAME was odysseus. and he shot an arrow through a whole bunch of ax handles then he massacred the jerks that tried to steal his wife.
labrys
A garden hoe is "une binette". The term "pioche" is often translated as "ax", meaning pickaxe.
Two-bladed ax, usually called a labrys.
It would be the "A" value/term. Standard from is Ax+By=C.
(ax)(ax) = a2 + 2ax + x2
If by "xn" you mean ax^n then the answer is "a"
double-replacement
Double Replacement
A double replacement reaction.
Ax + Bx + C is not a trinomial!
The difference is in the shape of the head of the ax.
an example of a three-term polynomial is: Ax2 + Bx + C. (that's Ax{squared})
