Rich Text Editor.To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph.An inline formatting menu will show up when you select text. Hit tab to get into that menu.Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.

    Allo LucioleInsolite4041,

    Merci pour ta question!

    Pour trouver l'aire de la partie hachurer, tu dois faire l'aire du rectangle - l'aire du carré.

    Par contre, comme il n'y a pas de mesure pour le carré, on peut supposer que le point G divise BC en deux. On a donc 3x+1 pour le côté du carré.

    J'espère t'avoir aidé!
