Bonjour,
Soit c le côté de l' hexagone.
On a 5.2²+(c/2)²=c²
==>c²=5.2*4/3
c²=104/15
c=√(104/15)=2,6331223544175332023251281391631...
Aire de l'hexagone= 5.2*c/2*6=41,076708728913517956271998970944
Je me suis permis de répondre en Français car l'énoncé était en Espagnol. (Thanks to Google translator)
The product of 14560 × 10 is 145600
Lets say cookies = x and days = y.
2x times y = 15.
8x times y = 45.
Both sides would be the same, so set them to equal ans solve for x.
3x+4 = 2x +7
Subtract 4 from each side:
3x = 2x +3
Subtract 2x from each side:
x = 3
The answer is X = 3.
